Why so shy?

Kendall and Kylie Jenner arrived at LAX with mom Kris today, and it seemed the teenagers didn't want to be seen traveling with their parent because they were hiding their faces as they made their way through the terminal.

The ladies were returning from the East coast, where they were promoting their new teen novel and making appearances at places like Barnes & Noble.

It's becoming even harder to keep up with the Kardashians!

50 Cent isn't the best actor, but he gave us a serious case of the giggles last night when he donned Angelina Jolie's Maleficent costume for a brief skit on Jimmy Kimmel Live. Seriously, the image above just made our week ... and that was before we heard him cackle in the clip below!

The rapper told the audience he had a big new project and added, “This one ain’t going to no Redbox." We just wish the bit was longer! In case you missed it, check it out below:

Jennifer Lopez and Casper Smart have split after two and a half years together, according to multiple reports.

"It has actually been an amicable process that started a few months ago," an insider tells Us Weekly. "It wasn't an easy decision, but they decided to stay friends ... Their relationship couldn't work with the distance. He started trying to establish his own life and career, and she is so focused on hers, and they just couldn't be all about each other anymore."

After several websites claimed that Casper was fooling around with transsexual models, we figured it would only be a matter of time. Last week it was reported that Casper hooked up with trans model Sofie Vissa, and a few days later The Dirty found a second girl, Xristina Marie. The site added, "According to our source the couple met in Miami and Casper Smart was 100% aware that Xristina is a transsexual."

Still, a source close to the couple told Us Weekly that the story was "100 percent not true," adding, "The scandal had nothing to do with it. He insists none of that is true and she believes him." The source adds that Lopez is "doing fine" and she's "focused on promoting the album. They are both in a good place now."

Lopez, 44, and Smart, 27, started dating in November 2011, just four months after she split from Marc Anthony, with whom she has twins Max and Emme, 6. Lopez was previously wed to Cris Judd and Ojani Noa, and from 2002-2003 she was engaged to Ben Affleck.

Wonder who J. Lo will step out with next?

Chris Brown's a free man now, and he celebrated his release from jail last night with girlfriend Karrueche Tran, his friends and a whole buncha red Solo cups at a Beverly Hills house party.

After just more than three weeks in the slammer in D.C., Chris has obviously put on a few pounds and let his hair grow a little. After tweeting to his 13.5 million followers, "Humbled and Blessed," and "Back to the Music and the Fans," Brown officially ended his relatively short stay of a 131-day jail sentence on Monday.

It's not all fun and games for Chris now that he's out, though -- he has to complete around 800 hours of a mandated 1000 of community service for his probation of violation stemming from his assault on Rihanna.

Chris' troubles ain't over yet!

Fresh from their honeymoon, Kim Kardashian and Kanye West were just itching to spend some quality time with their nearly one-year-old daughter Nori, so the couple pulled a totally normal parenting move and took her to a mommy and me class in Los Angeles on Thursday. Awww! And Kimye weren't the only famous faces there -- we caught Hilary Duff at the class as well!

After that Kim switched cars and headed to lunch in Beverly Hills, and at some point in the next few days she's set to travel to the Hamptons to shoot scenes for Kourtney and Khloe's spin-off show, and she'll be there for several weeks. Obviously she's bringing Nori with her, so Yeezy will be staying with them too, right?

Maybe. "It’s still to be determined whether or not Kanye will be heading out there as well," according to a source for Hollywood Life.

And speaking of being a hands-on dad, Kanye is reportedly taking "drastic measures" to beef up daughter Nori's security, according to Radar Online. “Kim and Kanye have been arguing over all of the exposure North got during the wedding,” a source close to the couple told the site. “He was frustrated that the baby was in public so much and he wants to make sure that now that all of those festivities are over that she’s protected.”

“Kanye isn’t trying to control any press about North," the insider added. "He’s genuinely afraid for her safety and doesn’t want people to be able to track her every move. He is talking to other really rich and famous people about how they keep their kids safe and what extra precautions he can take. He isn’t taking any chances."

But given how media-friendly the Kardashian family is, do you think he and Kim are butting heads about just how much they want to feature their darling little girl on the show?

She's definitely ready for summer!

Emma Roberts has been soaking in the sun with fiancé Evan Peters during her trip to Hawaii for the Maui Film Festival, and she just can't seem to resist showing off her toned bikini body in a variety of ensembles!

The actress shared a pic of herself in a bikini at the beach, and then she posed for photo at the big event in a crop top and pencil skirt with newly single Evan Rachel Wood and True Blood hottie Joe Manganiello.

She's giving her aunt Julia a run for her money in the looks department!

But is she a one-take wonder? We feel like Lady Gaga probably took several snapshots before settling on this one...

Gaga Instagrammed the pic above and wrote, "Day off sleepy girl," and while many celebs look frightening without foundation, eyeliner and lip gloss, she's quite the natural beauty! In fact, she sometimes looks scarier when she's all done up and wearing one of her crazy costumes...

Gaga takes pride in loving herself for who she is, and in a 2011 interview with Harper's Bazaar she stated, "Whether I'm wearing lots of makeup or no makeup, I'm always the same person inside." Still, she admits that she loves getting all dolled up, as she added, "I don't think I could live without hair, makeup and styling, let alone be the performer I am. I am a glamour girl through and through. I believe in the glamorous life and I live one."

She's using her beautiful face for a good cause!

Rihanna made an appearance at the Hard Rock Cafe in Paris today to unveil a new t-shirt that will raise money for The Clara Lionel foundation, which is a non-profit organization with a mission of improving cancer treatment in the singer's native Barbados.

The pop star started the charity back in 2012 in honor of her grandparents Clara and Lionel Brathwaite.

RiRi might be in France, but she's making headlines in London after her new Rogue perfume poster just got banned for being too "sexually suggestive".

She can do no wrong in our eyes!
