Kendall Jenner hung with Cindy Crawford's teenage daughter Kaia Gerber at Coachella on Friday, and the ladies looked amazing. Well, "ladies" probably isn't the right word, seeing as Kaia is FOURTEEN! Would you let your teen party at Coachella with a Kardashian? Hmm...

Here's what's interesting though. Just last month Harry Styles, who may or may not still be dating Kendall, paid a visit to Cafe Habana in Malibu, which is owned by Kaia's father. The One Direction star met with Kaia and her parents, so clearly she's tight with the cool kids in Hollywood...

Who else did we spot on the Empire polo fields? None other than a shirtless and super ripped Kellan Lutz, along with Brooklyn Beckham, who flashed his guns in a far more tasteful manner:

Casual Friday, anyone?

Yesterday a sweatpant-clad Ben Affleck headed to a doctor appointment in his vintage Chevrolet Chevelle, and from the clothes to the tired expression on his face, he looked completely worn out. Is it too much work? The stress from his divorce from estranged wife Jennifer Garner? Or was he up to something last night? We're not sure, but at least he planned ahead with a snack!

Earlier this week at at CinemaCon in Las Vegas, Warner Bros. chairman and CEO Kevin Tsujihara confirmed that Affleck will direct the upcoming stand-alone ‘‘Batman’’ movie. Hey, at least he has that to look forward to!

After being spotted yapping on the phone, Kanye West headed to his design studio in Los Angeles on Friday. The rapper wore a yellow shirt paying homage to Kobe Bryant, but don't be fooled -- this $65 longsleeve tee is actually from Yeezy's Pablo line. Sigh. Is he ever NOT promoting himself?

After handling his business, Kanye met up with wifey Kim Kardashian for a lunch date in Beverly Hills. He rolled up in his pricey Mercedes McLaren will his missus rode in her range rover, and the two went their separate ways after grabbing a bite.

In other news, Kim -- and her sister Kendall -- got a MAJOR diss from Calvin Klein during a recent talk at the Savannah College of Art and Design with former CFDA president Fern Mallis. Klein has not been involved with the design process at the fashion house since he sold it to Phillips-Van Heusen in 2002, and when asked what he thought of Kendall's My Calvins ads, he was not pleased.

"I’m sure she’s a lovely young woman," he began. "It’s not the kind of thing I would have done, even today. Justin Bieber, yes. When [I say] I like Justin Bieber in the Calvin Klein Underwear [campaign], it’s because I like him — not because he’s got millions of followers. Now, models are paid for how many followers they have ... If you take really exquisite photographs of the right people in the right clothes in the right location, and you put it online, that’s fine. Just putting any old clothes on Kim Kardashian, long-term, isn’t going to do a thing.”

Ouch! We wanna know what Kanye thinks of that...

Kylie Jenner, is that you?

Kesha arrived at LAX this morning to catch a flight to Nashville, and we couldn't help but notice that the singer has gone overboard on lip filler! She must have plumped her pucker in an attempt to look her best for her performance at Coachella. As we previously reported exclusively, the "Tik Tok" songstress will be the surprise guest at the music festival for weekend two.

Seeing as she's still battling Sony and Dr. Luke in court, we bet her trip to Tennessee is to sort out some legal issues before she takes the stage. The pop star is allegedly running out of money because of her binding recording contract with her accused rapist producer, so Coachella is actually a good way to get back on the scene and make some dough at the same time!

Free Kesha!

Prince William and Kate Middleton really are the picture-perfect royal couple! The duo went on a three-hour hike to Tiger's Nest Monastery in the Himalayas of Bhutan on Friday and looked like they barely broke a sweat!

On their second day in the kingdom of Bhutan, the royal parents hiked to the Prayer Wheel, which is the most sacred Buddhist spot in the country.

Kate opted for a notable pair of Penelope Chilvers knee-high boots which she paired with a nubuck vest from the Really Wild Company.

Director of the National Museum Khenpo Phuntshok Tashi explained that the centerpiece is a giant Prayer Wheel around a group of 22 smaller wheels. Visitors, who make the pilgrimage, stop at the wheel, chant and say prayers, spinning each wheel.

The climb culminates at Paro Taktsang, otherwise known as Tiger's Nest – one of the most breathtaking temples in the world and also the most spiritual place in the whole of Bhutan.

American traveller Lauren McKennan and her friends ran into the royal twosome as she and her crew headed down. McKennan told press, "They were pretty altogether. There wasn't a single trail of sweat. They stopped to talk to us for three to five minutes and were absolutely charming."

Umm they're perfect!

No wonder she's always walking around with that smug look on her face these days!

Kourtney Kardashian hit the studio to film scenes for Keeping Up with the Kardashians yesterday and then spent the rest of the day hanging with her kids, and we think it's nice that she took the afternoon to be a mom, because lately all she seems to be doing is boning Justin Bieber!

Rumors that the reality star and the pop star were having sex surfaced back in October, but then they sort of died down until recently, when People reported that the pair are still quietly doing the deed whenever he's in town. "They have hooked up a few times, including recently. It happens in L.A. He has met her kids, but they don't hook up around the kids. It's on nights when she has help and is able to go out," a source dished to the mag.

"Kourtney is great. Justin thinks it's cool that she is older and hot. She isn't clingy and has her own life. There are no bad consequences for Justin to hook up with her. She is very easy going and just makes it fun for him to be around her," the source added.

The mother-of-three clearly has no self respect. Not only did she turn a blind eye to Scott Disick's cheating for years, but now she's OK with sleeping with The Biebs even though she knows he's banging a handful of other b*tches!

Break out the blazers -- it's date night!

Ellen DeGeneres and her wife Portia de Rossi both donned blazers for a date night at Craig's in West Hollywood on Thursday night.

The 58-year-old TV host looked giddy as she held her 43-year-old wife's hand as they walked into the hotspot.

The comedian opted for a black blazer which she paired with skinny jeans and a floral shirt. The Arrested Development star selected a white blouse, white blazer and satin pants.

In a recent interview at ABC's Television Critics Association party, Portia dished on how much she loves Ellen.

"We're just really good friends and we talk about everything, and we never ever, ever lie to each other, like, not even the tiniest lies," said the star.

The Aussie continued, "And she's the only person I want to hang out with. Like, she is my best friend and I just want to be with her all the time."

Aww these two are adorbs!

Amber Rose stopped by the nail salon in West Hollywood on Thursday, and the curvaceous star was snapped with her luscious lips wrapped around a lollipop. Get it girl!

Amber recently weighed in on the upcoming nuptials of Rob Kardashian and her pal Blac Chyna, and she told Jezebel, "I don't think she'll have a maid of honor, but I don't know. I would hope so but maybe she just has too many friends for that. Sometimes you can't! When you have a wedding, and you have so many best friends, you can't just pick one or not have a maid of honor or pick your cousin or someone in your family."

"I felt like that was coming," she continued. "When two people love each other like that, you just know. You know what it is, just the way they looked at each other and the way they are together. It's cute."

Aww!
