We can only imagine how emotional this must have been!

By now, everyone has seen Caitlyn Jenner's iconic Vanity Fair cover, but it wasn't long ago that the Olympian and the VF team were going to extraordinary lengths to keep the first glimpses of her transition private until the time was right, they reveal in a new behind-the-scenes short documentary.

The 65-year-old reality star explains the isolation she felt during this process, and even breaks down at one point discussing the positive reaction she's received since announcing her plans to transition from male to female.

"I've basically been inside this house for three months. I haven't really left. It's difficult because I can't go out and be seen by the paparazzi. It was just hell. It was really, really tough on me," she confessed about the months leading up to the mag hitting the newsstands.

VF editor Graydon Carter admitted they brought in maximum security to protect the issue and Cait's privacy, which was important in ensuring the pivotal moment in history went down without a hitch. "He was at a stage in his life where he was going to make this seismic change. I thought this cover, if we got it right, with a great image from Annie Leibovitz, you've got this incredible cresting political issue of transgender…" he says in the video. "We brought in the security that we use for the Oscar party, for the Whitehouse Correspondents' Dinner... We had security at the photoshoot, security at the printer," he continues.

For her part, the E! starlet couldn't be more appreciative of the welcoming she's received as her new authentic female self. "It's been great, so many good people, and love and support. I had this one time where I looked from a distance and I just thought, 'Oh my god!' It was the first time I'd ever really seen an image of me, who I am. Over-the-top better than I ever thought I'd ever be, especially at my age. Seeing that image was powerful to me," she gushed while wiping away tears.

We saw more emotional moments on last night's I Am Cait premiere, including son-in-law Kanye West praising her for rising up against enormous public opinion and daughter Kylie meeting her for the first time on FaceTime.

As if things couldn't be better, her son Brandon and his wife Lea just welcomed daughter Eva James over the weekend, so she's a grandma again!

Brad Pitt breezed through Los Angeles International Airport on Sunday afternoon, and he wasn't exactly in the mood to strike a pose and chat with us, but the clean-shaven star did flash us a quick smile -- along with a peek at his freshly-dyed blonde locks AND his beefy pecs! No dad bod here....

While Brad seems fine, rumor has it he's on the verge of divorcing wife Angelina Jolie. And get this -- the National Enquirer reports that the couple may lose custody of their daughter Zahara. What?! While it sounds a little bit hokey, apparently 10-year-old Zahara has expressed an interest in going home to Ethiopia to live with her "real mother." While it was initially reported that Zahara was orphaned, some years later her birth mother, Mentewab Dawit, reportedly came forward and revealed that her family gave Zahara up for adoption.

"The kids flipped out when Vivienne landed a role in her mother’s film Maleficent," a source tells the tabloid. "Yet another bone of contention is that Shiloh has been tagging along with her mother on humanitarian work around the globe. Brad believes that Angie may be putting Shiloh in danger by taking her to refugee camps. Add this to Zahara’s desire to return to Ethiopia and it could set off the fight to end all fights." Yikes! Think that's true?

The women of the Kardashian-Jenner family never miss a chance to get all dolled up! And when we say all dolled up, what we really mean is putting their boobs and booties on display! It seems like every time we've seen Kourtney lately her tatas are nearly falling out of her top, which is almost more distracting than pregnant sister Kim's growing belly! Then again, it does seem like a pretty good way to show estranged baby daddy Scott Disick what he's missing...

Kim, Kourtney, Kylie, Kendall and Kris spent most of their Sunday together, and from Kim's baby bump to Kourtney's cleavage (not to mention yet another scandalicious outfit from Kylie!) there was a WHOLE lot to look at. The ladies (plus Corey Gamble) started off by heading to a bash in Hollywood to celebrate the birthday of Kris Jenner's mom, Mary Jo Campbell, and they later stopped by the Ivy in West Hollywood for lunch. Kendall and Kylie were also spotted with their grandma at Pantages after catching a performance of The Phantom of the Opera, so from parties to plays, it seems like the group had quite the busy day.

But where was Khloe? While the reality starlet did post a pic of herself with Mary Jo (she captioned the shot, "MJ x KoKo. She's a legend in my eyes! 😍"), we didn't see her or Rob out and about with the rest of the family....hmmm!

Bobbi Kristina Brown has died at the age of 22.

The only daughter of Whitney Houston and Bobby Brown passed away at Peachtree Christian Hospice near Atlanta, Georgia after being moved there in late June. She was surrounded by family and friends at the time of her death.

The Houston family said in a statement:

"Bobbi Kristina Brown passed away July, 26 2015, surrounded by her family. She is finally at peace in the arms of God. We want to again thank everyone for their tremendous amount of love and support during these last few months."

Brown was found facedown in her bathtub on January 31, and two days after the accident she was put on life support. In February doctors performed a tracheotomy on the aspiring singer, and a week after that she was taken off life support, but just a day later she was hooked back up after suffering several seizures.

In April Brown's grandmother Cissy Houston chatted with Entertainment Tonight and revealed that Bobbi Kristina was "not progressing at all." Houston added, "She's not gone yet, but you know, whatever the Lord decides, I'm ready for her ... I have nothing to do with that. That's His job. It's His territory, you know? And I understand it."

Shortly after Bobbi Kristina was put on life support, her father Bobby said in a statement, "We are asking you to honor our request for privacy during this difficult time. We are currently investigating the events that led to [her] hospitalization." Bobby made a point of telling the press that his daughter was not married to partner Nick Gordon, who is still reportedly at the center of the criminal investigation.

RIP.

Hopefully this is a good thing! After all, Kim Kardashian is been known for her heavily-painted face, among other things.

On Saturday Ashley Tisdale attended a Master Class held by celebrity makeup artist Mario Dedivanovic, and longtime client Kimmy K was there as Mario's special guest. Ash posted the pic above and wrote, "Thanks to @makeupbymario for inviting me to his #masterclass. Learned so much watching him do his magic on @kimkardashian." Wonder if Kim and Ash had anything interesting to talk about? After all, Ashley got her start on the Disney Channel and Kim rose to fame after her sex tape with Ray J hit the internet, so it's not like they really have that much in common...

In between acting and loving life with hubby Christopher French, Ash is set to launch her own fashion blog on Wednesday titled "The Haute Mess." We're thinking this will definitely be covered on her new website!

David Beckham is a regular at SoulCycle, but look who else we snapped there on Saturday morning! None other than Jessica Alba, who was absolutely glowing after a hardcore workout.

While it appears as though Becks and Alba had the same class together, they weren't snapped anywhere near each other on the way out, so who knows whether they chatted it up during their spin sesh. The soccer stud went out the front entry and darted right into his car while Jess exited in the back. She had a huge smile on her face and wore a shirt that read "Get Your Om Back" -- looking good, Jess!

After reports that there was cocaine at Kylie and Kendall Jenner's high school graduation party earlier this week, big sis Khloe Kardashian took to her Twitter to shoot down the claims.

Khloe tweeted:

"You guys will make up anything. No! No one was doing coke at a graduation party in broad day light with teenagers and 15 production cameras! We aren’t as wild as you want to believe. We were taking Jell-O shots though and you have to scrape the rim of the shot glass w ur finger to loosen up the jello in order 2 take it. Just say no to drugs kids! Drugs so not our style."

While Jello-O shots are certainly not as bad as cocaine, don't you think that's a little inappropriate as well? I mean, seeing as there were TEENAGERS at the party...

The drama started when Kylie posted a Snapchat video of a pal dipping his finger into a small cup, at which point fans began to speculate that the substance in question was coke. While Khloe's argument makes sense, we still can't imagine why alcohol was being served at a high school graduation party thrown by Kris Jenner and Ryan Seacrest! Then again, that could make for an interesting story line...

Kylie turns 18 in two weeks, so it seems like the party is only getting started. And while she may not have been doing drugs, she was wearing an "Eat Me Out" tee, which is totally appropriate for a 17-year-old:

Demi Lovato and Wilmer Valderrama were snapped at the mall in Sherman Oaks on Friday night, and we doubt they'd be shopping for engagement rings here, but it sounds like this will be coming sooner or later!

Last week the singer chatted with New Zealand's ZM morning radio show on Thursday, and when asked how would she react if Wilmer proposed she said, "I am very, very in love with him. I think -- we will probably wait a little bit longer, but -- if he asked me tomorrow I would say yes." Hint hint!

She continued, "Whenever we were first starting to date about like five years ago, because I was 18 and he was 30, people were definitely judgmental and even like my parents were kind of like, 'I don't know why someone his age is wanting to date someone so young?' After a while, everyone started to see that what we have is real and incredible and very special and we have been together ever since."

"Obviously my family loves him," she gushed. "You can see when we’re together or even just from our Instagrams that we’re very sweet to one another." Clearly! Demi recently posted a photo of the two snuggled up together and wrote, "My love... Always supporting me on set... At 4 am even if he has to get up to work at 8."

So, when is Wilmer popping the question? We're curious to see!
