The who's who of young Hollywood was in attendance!

Cody Simpson celebrated turning another year older with a birthday bash at The Nice Guy in Hollywood, and girlfriend Gigi Hadid was there along with Miley Cyrus and boyfriend Patrick Schwarzenegger and Justin Bieber. The Australian singer was presented with a pepperoni pizza cake, and it looks like it was quite the wild night!

The blonde pop star is the least famous of this whole crew, but it sounds like he might looking to raise his star power this coming year. "I'm putting together a pretty cool catalog of music. I moved record labels, so I kind of get a fresh start now doing it the way I wanna do it because now I'm kinda old enough to have the creative freedom and the tools to do it the way I wanted to do it," he recently told E! News.

If Kendall Jenner and Hailey Baldwin had been there, it would have been the whole "It" crowd of teens in the spotlight!

Benji Madden was out grabbing coffee at Bouchon bakery in Beverly Hills when he was asked about his recent wedding to Cameron Diaz and the possibility of starting a family, but he didn't have much to say… because it was actually Benji's identical twin Joel! Whoops!

Rather that correct our videographer, Nicole Richie's husband simply asks for a little privacy before grabbing his cup of joe and taking off in his ride.

Good Charlotte should change their name to Confusing Charlotte, because it's impossible to tell these two apart!

Gwyneth Paltrow sitting down with Howard Stern? Well that's an odd pairing!

But odd pairing or not --the leggy blonde had a sit down with the shock jock on his SiriusXM radio show and got pretty candid about some topics we didn't think she'd dish about -- Brad Pitt, Ben Affleck and everyone's favorite term to mock: "consciously uncoupling"!

In the interview, the mom of two talked about her three-year relationship with superstar Brad Pitt, whom she met when she was 22. "I definitely fell in love with him. He was so gorgeous and sweet. I mean, he was Brad Pitt!"

The Oscar winner also said that her late director-father, Bruce Paltrow, was heartbroken by their 1997 split. "My father was devastated. I was such a kid, I was 22 when we met. It's taken me until 40 to get my head out of my ass. You can't make that decision when you're 22 years old... I wasn't ready, and he was too good for me." She told Stern, "I didn't know what I was doing."

Paltrow also addressed her high-profile, three-year relationship with Ben Affleck, saying, "He was not in a good place in his life to have a girlfriend." Sounds like someone wasn't a very good boyfriend!

Chris Martin's ex also admitted her supportive parents wasn't so devastated by that break up, saying, "I think they appreciated how he's super intelligent and he's really talented and funny. They loved him, but they were okay with us not being together."

And of course when the Stern asked the actress, who is currently promoting her new crime caper Mortdecai, about using that oh-so infamous term, "conscious uncoupling," when she announced her split with the Coldplay frontman via Goop in March.

Paltrow said, "I made a mistake ... I didn't give it context. But it is a goofy term."

Yes. Yes it is. We are glad she's finally seeing the error of her ways.

That's one way to come to terms with it!

Khloe Kardashian is known for having a pretty intense camel toe, so when she rocked tight white jeans that showed it off in all its glory yesterday, she wasn't afraid to poke fun at her frequent wardrobe malfunction… she even gave it a name!

"Today I let Jen and Joyce not only do my hair and make up but I actually let them style me today. And I must say I love what these two ladies created - oh Camille the camel is trying to say hi! I hope she listens today," she captioned the above snapshot.

"I always have camel toe. It is what it is — I can't control it," the reality star previously confessed on an episode of Keeping Up with the Kardashians.

At least she has a sense of humor about it!

Hello boys! JLo is movin' in the neighborhood!

Wearing a geometric design by David Koma, Jennifer Lopez sizzled at the premiere of her sexy new film, The Boy Next Door, hosted by BodyLab in Miami.

In the film, Jennifer stars as recently divorced high school teacher who has a passionate one-night stand with her new, much younger neighbor (Ryan Guzman). Unfortunately, the pretty young thing turns out to be a student. Eventually, the ill-fated fling turns into a dangerous obsession.

And its possible that Jenny from the block has lit more than the silver screen on fire with her relationship with Guzman. The two seemed pretty chummy at a Golden Globes after party on Sunday, sparking the rumors that the 45-year-old and the 27-year-old were more than just costars.

The film moves into theaters on January 23.

We bet there was a lot of girl talk over pasta dishes!

Rihanna grabbed dinner with a female pal at Giorgio Baldi in Santa Monica last night, and the singer looked beautiful but a little tired in a grey sweatshirt, track pants and no makeup. Riri must still be recovering from her wild weekend at the Playboy mansion, where she reportedly enjoyed an intense smooching session with Leonardo DiCaprio!

The songstress and the A-list actor would be the perfect couple! Both enjoy vacationing, partying, and being carefree, so it was only a matter of time before their common interests brought them together, if it is indeed true that they are hooking up. The Titanic star's ex Bar Rafaeli said "Rihanna is everyone's type" when questioned the other day about what she thought of her former boyfriend getting together with the Bajan beauty.

Going from Chris Brown to Leo is what we call a major upgrade!

We know you can't stop and won't stop but seriously, Miley -- PLEASE STOP.

Miley Cyrus felt the need to expose her nude body, except for a bubble bath bush, for a very special issue of V magazine. This latest stunt just cements the fact that it's time the former Disney star just stop her wild antics and the grow the ef up. We get it Miley, you're a dirrrrrrrty girl!

The 22-year-old posted the snap on Instagram, along with the caption, "order yurrrr copy nowwwww cumzzzz w ol school pull out postahhhh photography by @cheythom fuck yaaaas weez a bunch of happy hippies ova hurrrr! ❤️ Muah Vfam!"

Huh? What? Is that English?

We are so ready for Miley to fade into obscurity or at least do a Barbara Walters special where she has a heart-to-heart interview about that crazy time in her life when she felt she exposed her penchant for using drugs and showing off her nipples to the world on a somewhat daily basis -- but now she's leading the sober, more clothed life. Yeah -- we have a feeling that interview's not happening any time soon ...

We just hope the Destiny Hope's future holds a life of grace and dignity and not so many nude soapy selfies. Our eyes can't take much more of this!

Meanwhile, it appears as though Miley's trying to get into the Kennedy clan any way she can. Her 20-year-old brother Braison (yep, apparently that's a name) is dating boyfriend Patrick Schwarzenegger's older sis, Christina, reports TMZ.

Jackie Kennedy is rolling in her grave ...

K-Stew's got a new 'do!

Kristen Stewart attended a screening of her upcoming film Still Alice in NYC last night, and for once the actress didn't look like she had rolled out of bed! In fact, she seems to have gotten her hair done for the big event, as she now has darker brown locks and a fresh cut.

The Twilight star opted to wear a sleek black dress and heels rather than her usual dirty jeans and sneakers, and we must say we far prefer this look! We may think of her as having a "give-no f**ks" attitude, but she insists that couldn't be farther from the truth. "I’m like, actually, no one gives a f**k like me. No one gives more of a f—k than me. It’s just ironic to me. I’m always like, really?” she confessed to Salon magazine.

That's not to say she loves living life in the limelight, though! "I have not always been completely comfortable being shoved into the brightest, most blinding spotlight you can imagine. People always ask if I chose the projects I’ve chosen because I’m trying to redefine myself or people’s perception of me. Uh, no. In a word, nah," she added.

We're starting to like her more!
