Auntie Koko is head over heels!

Khloe Kardashian was one of the first people to meet sister Kim's newborn baby boy Saint West, and the proud reality star can't help but gush about the newest addition to the K clan.

"My little nephew was born. He is so cute and so perfect. I love him and mommy and daddy are doing fantastic," she said during a live stream with her fans.

The little guy's name was announced yesterday, but apparently Kimmy K and Yeezy have been calling him Saint for months now, because they believe he was a miracle baby due to the brunette bombshell's fertility and pregnancy struggles.

Khlo seems like the most maternal of all the sisters, so we can't wait for her to have a brood of her own!

Bieber is not gonna like this news …

On Friday night, Selena Gomez and One Direction's Niall Horan were caught kissing at a birthday party and it turns out that on Saturday night the duo had a romantic date at Santa Monica Pier.

Needless to say, these two wanted to get spotted out and about otherwise they wouldn't have had such a public date.

Camera-ready fans snapped the twosome riding roller coasters and playing boardwalk games together over the weekend and posted pics and video on social media. The twosome were hanging with some pals -- but they were all about each other.

For the outing, the One Direction bandmate went incognito in a pair of thick-rimmed glasses, while Gomez opted for a black top and pants.

We think the choice of the Santa Monica Pier is especially interesting since that's where cameras caught Gomez and Bieber on their first public outing way back in 2011.

Burn, Bieber!

Kim Kardashian gave birth to her second child Saint West on Saturday, and though "mother and son are doing well," apparently the delivery was hell!

Kim had placenta accreta, a serious pregnancy condition where the placenta grows too far into the uterine lining. The condition can cause severe blood loss after delivery, and TMZ reports that the reality star has been describing her labor as the "most painful experience ever."

Kim suffered from the same condition while delivering daughter North, and though a C-section is generally advised with the condition, Kim reportedly did it all naturally. She's a real trooper! But is she done having babies? We'll see!

Kim is still holed up in the hospital in a $4,000-a-night birthing suite, and big sis Kourtney was reportedly by her side during delivery. She's since been visited by Yeezy and most of the rest of her fam.

Kourtney Kardashian stopped by a friend's house in West Hollywood on Monday, and the reality starlet looked amazing in a leather jacket, black leggings and a cropped top. We love that she's flaunting her abs in the middle of December!

In other news, Kourt finally relaunched her blog this week -- and debuted her new app, which is simply called Kourt. Sisters Kim, Khloe, Kendall and Kylie's apps were released in September, but it sounds like Kourtney's will be very different from everyone else's. "I cannot wait to share my life with you," she said in a video message to fans, adding that she'll be sharing "original posts on topics including personal recipes, influencer Q&A's, healthy living tips, home design ideas, shopping and beauty guides and kid-centric obsessions." Is she trying to be the new Gwyneth?

"I am so happy to finally have a space where I can share my obsessions and the things that I am most passionate about," she said in a press release. We're curious to see whose app is the most successful ... you know the ladies are totally competing with one another!

Selena Gomez debuted a teaser for her new song "Hands to Myself" on Facebook last night, and all we have to say is hot damn!

SG tweeted the clip and wrote, "Catch the sneak peek of my "Hands to Myself" Video featuring the new Beats by Dre Pill!" Even with the shameless product plug, we love the video -- you know Selena's ex-boyfriend Justin Bieber must be kicking himself watching this!

From the bangs to her bangin' body (and sexy undies), Selena looks incredible. She prances around a fancy house in her skivvies, and we see her getting ready to make a run for it as cops pull up to the mansion. We can't WAIT to see the rest!

Auntie Ky is back in LA!

Kylie Jenner has spent the past several days partying it up in Miami for Art Basel, but the reality star headed back home today to meet sister Kim Kardashian's newborn son Saint West. The 18-year-old paid tribute to her brother-in-law in her Yeezus t-shirt, which she paired with white jeans and a leather jacket.

We couldn't help but notice that the youngest of the Kardashian-Jenner clan went to the art festival without boyfriend Tyga. Something tells us their relationship is on its last leg, which may explain why she's been spending so much time with A$AP Rocky. Perhaps it's time to trade up?! T-Raww is allegedly none too thrilled about his girlfriend's new friendship with his rapper pal, though.

“Tyga’s not happy at how close A$AP and his girl are getting. Tyga doesn’t care if he is cool with A$AP, point is, it’s disrespectful for him to be all up in Kylie’s face when he knows damn well he and Kylie don’t have the most solid foundation," a source dished to Hollywood Life.

"Tyga’s equally upset at Kylie but won’t tell her that. He doesn’t want to appear weak or if he’s stalking her but her closeness to this dude is cause for concern. Tyga’s a rapper and he’s not stupid. He knows the game. He knows that some rappers like to go through women fast like they’re running a red light. He ain’t saying A$AP is that guy. But then again, you never know," the source added.

There's no shortage of things to film for the family reality show, that's for sure!

Kristin Cavallari's brother, Michael Cavallari, appears to have gone missing in Utah. The 30-year-old disappeared over a week under suspicious circumstances.

On Nov. 27, the Grand County Sheriff's Office received a report that there was an abandoned Honda Civic along Interstate 70. Authorities identified Michael as the driver after finding credit card receipts in the car, which led them to a convenience store in Monticello, Utah. The convenience store had security footage of Michael, confirming he was the one driving the vehicle.

The Deseret News reported that Cavallari's laptop and cellphone were found in the empty car, which seemed to have hit a large rock on the side of the road. The car's engine was running and the airbag was deployed.

Grand County Sheriff Steven White told FOX411, "Right now everything is pretty status quo. We are conducting follow ups, and there is not much more to add to that. We are still out talking to people trying to piece things together."

The sheriff added, "We're combing the area for anything we can find." White told the paper, "We're deeming it suspicious, but there's nothing to indicate anything one way or another. The vehicle was just abandoned."

Kristin and her family have remained silent about the disappearance until earlier today. The former reality star, who just gave birth to a daughter, has tweeted to thank people for their support during this trying time.

I appreciate the thoughts &prayers that have been extended to me & my family. I have such gratitude for those that have shared their support

Baby Boy West finally has a first name!

Kim Kardashian and Kanye West have finally decided upon a name for their son, who was born on Saturday. We'd like to introduce the world to ... Drum roll, please ... Saint West! Kanye has often likened himself to religious figures so we aren't surprised at the name, but we aren't loving it. At least they didn't go with God West, King West or Jesus Christ Our Lord And Savior West.

The baby boy weighed in at 8 pounds, 1 ounce!

Kimbo induced labor three weeks before Saint's Christmas Day due date after there were complications with her daughter North's birth in 2013. Doctors thought it would be safe for her to have the child early because of her medical history.
