Kourtney Kardashian took daughter Penelope and son Mason to Pedaler's Fork in Calabasas on Sunday for brunch, and we're not sure where Scott Disick was, but Kourt didn't seem to mind!

And even though we've heard rumors for quite some time that the 35-year-old reality star is having a boy, it was finally confirmed it on last night's episode of Kourtney and Khloe Take the Hamptons.

It was actually Mason who broke the news to the family, and auntie Kim videotaped the moment when the 5-year-old revealed his unborn sibling's gender. Mason ran into the room with a blue stick with a star on it, but after that there was an awkward exchange with Scott and Khloe. "You’re not that excited?" Khloe asked when Scott appeared disappointed that he wasn't having a daughter. "No, I’m fine now," Scott replied. "I’m excited.”

And he wasn't the only one! Mason admitted that he wanted a little sister, but Khloe was able to change his mind. "Girls don't like aliens and Lego guys," she said. "When you have a brother you can say 'Look at all my Lego guys, brother.' You get to be rough and you can boss him around because you're the older one." Ha!

Celeb besties and their babies!

Jessica Alba and pal Jaime King brought their kids to the park for a playdate yesterday in L.A., and the whole group looks like they had a grand ol' time! The blonde model's hubby Kyle Newman came along for the fun, but the actress' husband Cash Warren missed out on the action.

The starlets' children ran around on the playground together, and the Hollywood beauties even took turns on the swing set when they weren't on mommy duty. It seems they have both put their careers on the back burner for motherhood and have never seemed happier!

While most people are bundling up with scarves and hats, Kendall Jenner is taking it all off for Love Magazine's online advent calendar.

The 19-year-old model strips down to her underwear and dances to Katy Perry’s "California Girls," and her video, which was shot by Doug Inglish, was just revealed today. Miranda Kerr was the first hottie to shoot a clip for the magazine's sexy video project, and Victoria's Secrel Angel Lily Aldridge appeared on the December 2 spot. It's only December 8, so we have a feeling there will be all sorts of goodies in store until Christmas!

You aren't going to see Lady Gaga dressed in sweat pants to walk her precious pup around the Big Apple -- but we wouldn't expect anything less stylish from the Mother Monster!

Wearing a ballgown, the 28-year-old singer was all done to go on a dog walk with her adorable French Bulldog, Asia, over the weekend.

While the "Bad Romance" singer may be all smiles, her four-legged friend definitely doesn't look so jazzed about the stroll around the city.

Aww!

These two need to call it quits once and for all!

Chris Brown publicly declared he and on-again-off-again girlfriend Karrueche Tran were dunzo during a concert over the weekend, but that was just the beginning of what quickly became a mudslinging match between the pair on social media! Among the R&B bad boy's gripes? His former lady love never visited him in jail during his four month stint earlier this year, she hooked up with his nemesis Drake, and she never appreciated his love. Breezy sounds like a whiny little baby!

"We've got scars, some of them u gave me, some of them I've caused. That ride or die act we have been fooling the world with obviously ain't working. I was locked up for damn near 4 months and only got 1 visit from you while u was hosting parties and taking secret trips to Toronto, going on dates with Drake!" he posted on Instagram before deleting the message. "When this relationship first started u knew what it was and even participated in threesomes," he continued. "I slowed all that shit down. So let's not try to save face for public opinion because I don't need to play victim so people can take my side. All these celebrity n---as ain't s--t and focus only on themselves. I made it clear to the world who my girl was and made your life equal to mine even at the cost of me not focusing on my career at times. So miss me wit the bulls--t. No y'all know the real," he continued.

The rapper's outburst comes as a response to a telling inspirational quote and words of advice the model posted on her own social media after news broke of his concert diss. "When something bad happens, you can either let it define you, let it destroy you or let it strengthen you. The choice is yours," she wrote. "I refuse to be repeatedly mistreated especially by someone who claims to love me. That's not love. Yes, I have not been so smart before in the past but I made a promise to be a better and stronger woman and I'm keeping that promise. If you can't love me the right way, then don't love me at all. Don't be mad at me because I prefer to be happy," she added.

It sounds like the bipolar diagnosis the "Loyal" singer received during anger management rehab might have been right on point, because it appears he's already having a change of heart! "Being young and dumb is one of my strong suits and emotional at best. I love hard and react impulsively when I'm hurt at times. I don't think social media is a place to air out or hash out personal problems and a n***a feel hella WACK for doing it. So I AM APOLOGIZING! I live in a glass house and the same s**t that makes me great also is my curse. Everybody know I love that girl. I don't care how my image might look to the public because I'm still gonna be the best at what I do. I just want my baby girl to know I apologize," he vented.

It still baffles us that anyone would date this idiot in the first place!

And we're still overwhelmed by his freshly peroxided hair!

On Sunday Justin Bieber stopped by West Coast Customs in Burbank for the auto shop's grand opening, and when he left, there were literally hundreds of screaming fans waiting for the 20-year-old pop star. Bieber patiently signed autographs and posed for pictures, but after a while even he looked a bit overwhelmed by all the love from his Beliebers!

Kris Jenner's new boy toy Corey Gamble helped control the crowd, and Bieber's usual team of bodyguards were on hand as well. Justin posted a pic on Instagram and wrote, "Thanks @westcoastcustoms for a great day," and they re-posted his shot and wrote, "Welcome JB. Keep the rides coming and we'll keep the creativity flowing. #illest #wcc #westcoastcustoms." He already has a cheetah-print Audi R8 and a chrome Fisker Karma, so we're curious to see what kind of a whip these guys design for the singer next!



We're still undecided on Bieber's new 'do, so tell us how you feel about it!

Kanye West, Kim Kardashian and little miss Nori took a red-eye from New York City to Los Angeles on Saturday night, and everyone appeared a bit grumpy when they landed on Sunday morning.

With Kim and Kanye's business trips (AND Kanye skipping out on the Kardashian family's Thanksgiving) the trio hadn't been together for about three weeks, so they spent all day catching up, right? Nope! Not long after returning to his Hollywood Hills home, Kanye ditched his black outfit for a super feminine tweed coat and headed to the recording studio. Maybe he had enough of Kim and Nori on the private plane?

When we first got wind of trouble in paradise between Kim and Kanye, a source close to the couple told X17online exclusively, "Kim is starting to give up; she feels like Kanye doesn't care about the family and he puts work first all the time. When Kanye goes into work mode - like he is with his new album right now - Kim and Nori get tuned out and it pisses her off." Sounds about right!

But things must not be that bad, because later on Kim got all dolled up for "date night" and posted this sexy selfie on Instagram ... and yup, it's definitely from a mid-dinner bathroom break:

On Sunday night Beyonce and Jay Z stepped out with daughter Blue Ivy for the premiere of Annie at the Ziegfeld Theatre in New York City, and we can't believe how much the celebritot has grown over the last few months!

Bey occasionally posts pictures of her 2-year-old daughter on Tumblr and Instagram, but little Blue usually has her back to the camera, so we seldom get a peek at her face. It's kinda amazing how much she looks like both of her parents -- and those expressions!? Even Jay couldn't help but crack up when his little girl made a series of silly faces and hand gestures...

The trio then went to the Skylight At Clarkson Square for an after party where they mingled with all the film's stars. Jay is one of the producers, and though he initially cast Willow Smith in the role of Annie, Oscar-nominated Quvenzhane Wallis later took the part. Will and Jada Smith are still producing the film, so it looks like they were at least partially involved in the decision, but we bet everyone's breathing a sigh of relief -- especially after that ridiculous article that came out last month! (You know, the one where Willow said school was for suckers and that she writes her own books because she doesn't like anything else available to her?)
