Caitlyn Jenner broke the internet with her Vanity Fair cover yesterday, and her transformation has been so incredible she even caught one of her stepkids off guard!

Kim Kardashian attended the CDFA Fashion Awards on Monday night, and she was happy to chat about Caitlyn's big debut. But get this -- Kim, who just announced that she's expecting her second child with hubby Kanye West, revealed that her brother Rob had no idea who Caitlyn was!

Kim told Access Hollywood:

"It was so funny because all the girls, we knew that Caitlyn was shooting this but my brother had no idea. So I sent it on a mass text to everyone and my brother was on it and he goes, 'Kim, why are you sending me this? Who is this woman? And why do I care?' And I was like, 'Rob, that's Bruce! That's Caitlyn!' And he was like, 'Oh my god, she's beautiful!' And then he called her and they had a lovefest and it was so cute. But the moment was so funny."

Kim already tweeted her congrats to Caitlyn, and she had more words of support for her stepmom. "This is Caitlyn's moment and it's her time to express herself and just be herself, and that's really what life is about," she added to Extra. "She just wants to help people that don't feel comfortable in their own skin, just to be confident in who they are."

Caitlyn's mom Esther told Access Hollywood, "She's beautiful! [Caitlyn] is… so much more at ease." But it doesn't look like she's quite ready to say goodbye to her son. "I still have to call him Bruce," she added. "His father and I named him that. It's going to be a struggle for me to get used to the change, but happily so… I'm very happy for him – or her!"

Caitlyn, who has now amassed over $2 million Twitter followers, had more thoughts on her transition. She told VF contributing editor Buzz Bissinger:

"It's funny, my mother, my mom, she has not met Caitlyn yet. We’ve talked on the phone, she is coming down... In about a week and a half... I’m sending a plane to go pick her up, and my sister, because she’s 89 years old and cannot get on the airlines, but she has to come down and, you know, we have to do this. For my mom I’ll send a plane. What I told her, 'Isn’t Caitlyn a much better friend?' Bruce, he would never send a plane. No, no, no, what a jerk the guy was, okay, Caitlyn is like, 'Send the plane. Mom, we’re sending a plane, we’re going to go pick you up and bring you down here'... It seems like she has a lot more friends than he ever had."

Caitlyn continued:

"I’m just going to go live life, I’m going to go enjoy life. I have nothing left to hide. I am kind of a free person, a free soul. [Up] to this point I would wear, you know, Bruce would wear, you know, sweatshirts with hoods on them so paparazzi can’t get pictures and all that kind of crap, and I didn’t want them to see if my fingernails were polished or, you know, on and on and on. It was just hell. To be able to wake up in the morning, be yourself, get dressed, get ready to go out, and just be like a normal person. That’s a wonderful feeling to go through life. I’ve never been able to do that; it’s always been confusion, it’s always been, you know, I’ve got one side [with] boy clothes, the other side’s women’s clothes. It’s like I cleaned the whole closet out -- the boys stuff is gone."

So what do other folks have to say about Caitlyn saying goodbye to Bruce and coming out to the world? Though the showbiz community has been overwhelmingly supportive (fellow trans star Laverne Cox penned a thoughtful note on Tumblr), last night Drake Bell (we actually forget why he's famous) ruffled feathers when he tweeted, "Sorry…still calling you Bruce." After receiving a number of angry responses, the actor then added, "I’m not dissing him! I just don’t want to forget his legacy! He is the greatest athlete of all time! Chill out! Calm down children."

We simply cannot keep track of the revolving door of ladies who are willing to hook up with Justin Bieber at the drop of a hat! And apparently, neither can the security guards at Bieber's favorite Los Angeles haunts!

On Monday night the Biebs brought number one bae Hailey Baldwin to The Nice Guy in Hollywood, and the 21-year-old pop superstar was joined by Cody Simpson and Madison Beer at the venue for an impromptu gig. Bieber has been performing at a number of small spots in Los Angeles over the last few weeks, so we're happy to see him back on stage.

But back to Hailey! After parading new fling Jayde Pierce around last week while Hailey was out of town, it seems like he's heating things back up with his favorite Baldwin. But he failed to let security know, because when the leggy model tried to hop in the car with her beau, club security mistook Hailey for a fan and shouted, "What are you doing?!" before finally letting her in the car. Oops!

Misunderstandings aside, it looks like the crew had a blast though:

She reminds us of an old Hollywood icon!

Caitlyn Jenner, who shed her former persona Bruce in a bombshell Vanity Fair spread released this morning, is every inch the stunner in these newly leaked photos, and we almost can't believe that she was able to keep her feminine self under wraps for so long, because her as a woman seems so much more fitting!

In one image, the former Olympian dons a sexy red dress with matching lips while sitting in her sports car, and in another she shows off her new breast implants while lounging in her dressing room. We bet Kris Jenner is none too pleased that her ex is hotter than she is now!

Another person that is probably not so pleased? Stepdaughter Kim Kardashian! Although we have no doubt that she's supportive of her stepdad, her pregnancy news got massively overshadowed by this reveal!

We were all for Caitlyn transitioning, but we really didn't expect her too look quite this glamorous! Nobody is going to care about keeping up with the Kardashians when we can now Keep Up With Caitlyn!

She's so unbelievably gorgeous!

Bruce Jenner gave the world what they've been waiting for by shedding his male persona and revealing his true female self as Caitlyn Jenner on the cover of the newest issue of Vanity Fair, and we have to say she looks so much happier than the Olympian ever did as a man. The 65-year-old showed off her new physique in a white bodysuit, and she definitely just made history in the classiest way possible!

"The last few days of doing this shoot was about my life, and who I am as a person. It's not about the fan fare, it's not about people cheering in the stadium, and it's not about going down the street and people giving you the 'that a boy, Bruce' pat on the back. This is about your life. Bruce always had to tell a lie. He was always living that lie. Every day, you always had a secret, from morning until night. Caitlyn doesn't have any secrets. As soon as the Vanity Fair cover comes out, I'm free," she explained to the mag.

“If I was lying on my deathbed and I had kept this secret and never ever did anything about it, I would be lying there saying, ‘You just blew your entire life'," she added.

As soon as this cover hit the web this morning, Caitlyn was receiving praise from family members and Hollywood celebs alike! Here are some of the reactions:

Kendall Jenner - "Now that's a cover."
Kylie Jenner - "My angel on Earth! #caitlyn."
Khloe Kardashian - "We were given this life because you were strong enough to live it! I couldn't be prouder!!! Caitlyn, you are beautiful!!!!"
Kim Kardashian - "Caitlyn Jenner for Vanity Fair. Annie Leibovitz! How beautiful! Be happy, be proud, live life YOUR way!"
Gigi Hadid - "As soon as the Vanity Fair cover comes out, I'm free." HI CAITLYN, YOU ARE BEAUTIFUL"
Ellen Degeneres - "My hope for the world is that we can all be as brave as Caitlyn Jenner."
Bella Hadid - "body chills. this is BEYOND. so amazing."
Lady Gaga - "Caitlyn, @Caitlyn_Jenner thanku for being a part of all of our lives & using your platform to change people's minds."
Monica Lewinsky - "insisting on a different ending to her story is EXACTLY what @Caitlyn_Jenner is doing. she is helping so many. BRAVA!"
Lena Dunham - "I just want Caitlyn Jenner to take me out and teach me how to drive a stick shift in heels."

She just started a Twitter account, and her first message was to thank fans and express how happy she was to be moving forward as Caitlyn. "I'm so happy after such a long struggle to be living my true self. Welcome to the world Caitlyn. Can't wait for you to get to know her/me," she wrote.

Kim thought she was the only one capable of "breaking the Internet," but clearly not! All we can say is wow, you go girl!

😭😂😂😘😘 @mikeyarana I'm not gay but even if I was that's not an insult

The Biebs makes the most of his flights!

Justin Bieber is a filthy rich mega star, so naturally he can do whatever he pleases! This time, JB decided to pull some tricks on his $1800 Hawk skateboard while on his private jet, and he chose to spin around and jokingly plant a smooch on his bodyguard Mikey Arana!

"I'm not gay but even if I was that's not an insult," he captioned the video. We all know that the Canadian crooner loves the ladies, but apparently he's not shy with his affection for all the closest people in his life.

The "Boyfriend" crooner has been making headlines the past few days, with rumors swirling that he will join The Voice as a coach next season. "This last season of The Voice had its finale be the least rated ever and Mark Burnett has taken notice. He wants to mix it up to get ratings up and get younger viewers to watch the show. The first thing the producers plan to do is change up the judging line-up, and the source says that “one of the seats the show wants to fill is [with] Justin Bieber," a show source dished to Hollywood Life.

Also, the chart topper's upcoming album isn't set to drop until December, but fans got a preview of his new song with Kehlani when his producer pal Khalil posted a clip of the tune to Snapchat, which was quickly uploaded to YouTube.

Lots of things in the works for our favorite bad boy!

These two are about the only members of the Kardashian clan NOT making headlines right now!

Kourtney Kardashian and her partner Scott Disick took their kids Mason and Penelope to the park in Malibu yesterday, and it seems as if they just wanted to spend a little quality family time together before some very big announcements were made by Bruce Jenner, now known as Caitlyn, and Kim Kardashian!

Kimmy K announced she was expecting her second child with Kanye West on the mid-season finale of Keeping Up with the Kardashians last night, and we thought that news would dominate headlines all this week.... until Bruce revealed his female persona on the cover of Vanity Fair this morning!

The majority of the family has commented on Caitlyn's big reveal, but matriarch Kris Jenner has remained silent thus far. The famous momager hit the gym early Monday morning in Beverly Hills, and we spotted her talking on her phone as she made her exit after her workout. Maybe she was getting the call that her former husband's bombshell was dropping?

We literally can't keep up!

At first we thought Lewis Hamilton was dating Gigi Hadid, but then there were rumors that he was after her BFF Kendall Jenner. Either way, Lewis was partying on a luxury yacht with the girls (plus Hailey Baldwin and Bella Hadid) in Monaco last week, so there was definitely SOMETHING going on!

So what does Lewis' former fiancee Nicole Scherzinger have to say about it? Well, nothing, but when asked about it last night at LAX, the singer was all smiles.

Maybe she doesn't care? Or maybe she knows that Lewis' fling with Kendall (or whoever) won't last? After all, just a few weeks it was revealed that Lewis was breaking into the music biz -- and that one of his new tunes was going to be a song for Nicole called "J’adore"!

We have a feeling this love story isn't over yet ... watch your back, Kenny!

Maybe someone should have paid more attention to Kylie Jenner when she was a kid ... The 17-year-old sexpot Instagrammed two skin-baring bikini pics of herself over the weekend and made it clear how much she needs validation. Read a book and put on some clothes little lady!

At this point we think the teen is really trying to give sis Kim a run for her money for the title of "Sexiest Kardashian."

In one snap, Kylie sits on a plush red couch and shows off her body while sitting next to a pit bull. The photo has a caption that reads, "Dogs couch now." Huh? We guess that's the kind of stuff you caption your posts when you go to the mall instead of high school ...

The other pic features the brunette's bikini-clad torso, sans caption. We think it would work if she'd just simply written, "Tell me I am worth something."

Sometimes we just want to give Kylie a hug and say: "Kylie, you don't need to post sexy photos of yourself for people to love you." But mostly we want to mock her.

Meanwhile, Tyga's young temptress has been trying to polish her pipes and learn how to sing. Umm maybe she should quit while she's ahead and learn to read?
