Models

Hailey Baldwin's looking a whole lot more grown and sexy than any other teen Justin Bieber might be seeing these days.

The 19-year-old flaunted her model figure Tuesday night in a crop top at the UGG Classic Street event in NYC ... her abs out and gleaming.

Seems like a clear message to Justin ... look what you're missing out on, bud.

Model Mara Teigen's new mystery boyfriend footed the $50,000 bill for her 22nd birthday, and the luxurious event had everything you'd want at an all-chick celebration ... except pillows.

Mara's party went down Sunday at the Beverly Hills Hotel in the Presidential Bungalow suite, which goes for about $27k a night. Dude also threw in a 6 ft tall orchid arrangement for $3,500 and a $2,500 cake. Not to mention the $12,000 diamond Cartier bracelet she got as a gift.

We're told she's been with the BF for about 8 months, but wants to keep his identity under wraps. And if he's gonna keep dropping this kinda coin, we say ... no need to rock the boat.

As for the guest list ... Justin Bieber's recent fling, Sahara Ray, "DASH Dolls" star Durrani and Carl's Jr. model Emily Sears were all there in white swimwear.

Still ... no pillow fight. Bummer.

Bella and Gigi Hadid's little bro is NOT teaming up with an ex-con -- no matter how much of a handsome bastard the guy is.

Jeremy Meeks -- the former Cali state prisoner known as Dreamy McMug Shot -- posted a pic with Anwar Hadid ... which became a thing on the Internet, and started rumors the guys were doing a modeling shoot together.

Sources close to Anwar tell us he and Jeremy were introduced in Bev Hills last week, and Jeremy asked for a pic because he's a fan. Anwar obliged because he's a nice guy.

Jeremy's no dummy though -- he's trying to make it big in modeling, which is probably why he didn't caption the photo.

Never hurts to be Hadid-adjacent.

Guns N' Roses knows what matters most when you're playing in L.A. ain't your instruments -- it's how attractive your audience is, and they made sure to stock their show with hordes of hot models.

TMZ has learned the GNR team fired off an email to Photogenics -- an L.A.-based modeling agency -- inviting every female model on their roster to Friday's show at Dodger Stadium.

We're told the 50 or so models who accepted got hooked up with free seats in the first couple rows, backstage passes and a spot on the guest list at the Roosevelt Hotel after-party.

There's only one rule: no boyfriends or non-models allowed. The invite strictly forbids +1s.

Translation: Leave your ugly friends at home.

Bella Hadid's nude spread in French Vogue got the thumbs up ... twice.

We caught up with the model Wednesday at LAX and our photog gets straight to the point about letting it all hang out across the pond. Check out the vid ... Bella's BF, The Weeknd, got himself quite the exclusive.

And Yolanda didn't mind.

Charlotte McKinney swaps beaches like she swaps boyfriends.

This time Santa Monica beachgoers got an eyeful.

The Carl's Jr. model used to be a Malibu regular, but that was when she was dating Stephen Dorff, who has a beach house there.

More insanely hot action from Kylie Jenner's birthday fiesta -- this time, her smokin' hot model friends are grabbing handfuls of each other's asses ... and catching it all on camera.

Hailey Baldwin, Bella Hadid and the rest of the crew threw on their skimpiest bikinis and headed out on a yacht in Turks and Caicos ... taking turns slapping each other's butts and taking pics.

The theory that 2 really good looking people will almost certainly produce really good looking offspring was proven true by Lisa Rinna, Harry Hamlin and their model/daughter, Delilah Belle.

The 18-year-old just signed a multi-year contract with Elite, which has got other offspring of famous people ... like Lizzy Jagger, daughter of Mick.

COOL -- UFC star Alan Jouban got to make out with Gigi Hadid for a Versace commercial.

COOLER -- His wife LOVED IT!

We're betting Justin Bieber's already had a close-up view of the birthmark in this pic -- can you spot it? It's okay if your eyes didn't go there first.

Model Sahara Ray's the chick the Biebs is cavorting with in Hawaii. Check out the pics ...the Aussie's fantastic curves are what dream vacations are made of ... if you're Justin.

Here's supermodel Adriana Lima carrying the Olympic torch through the streets of Rio Thursday night ... and as far we know, nothing bad happened.

The opening ceremony is set to go down Friday afternoon -- Gisele is rumored to be a part of the show and Pele is expected to light the Olympic cauldron.

Ireland Baldwin's doing wonders for the sequined collars and cuffs industry ... modeling a set of 'em in the nude.

The 20-year-old model showed off just about everything for a "treats!" shoot that features her in see-through tops, mesh tops and NO tops at all -- and we scored this behind-the-scenes video.

Her mom, Kim Basinger, did her first fully nude shoot for Playboy when she was 29 years old.

Ireland's not just curvy ... she's ahead of the curve ... and you can get it all here.

Formula One champ Lewis Hamilton is having a GREAT day -- partying in Barbados with a half naked Chanel Iman ... who's stealing the show at one of the hottest festivals in the world!

It goes down in the DM ... at least, that's how it went down with Cristiano Ronaldo, who social media pimped his way into a hangout session with Casi Davis, TMZ Sports has learned.

The woman who claims she's pregnant with Julian Edelman's baby is telling friends she's on great terms with the NFL star ... and hopes he's a big part of their daughter's life.

We're not really sure why Irina Shayk even bothered with this bikini.

The supermodel was on vacay with Bradley Cooper -- they moved on to the Italian isle of Sardinia.

Looks like Irina was solo on the beach as her butt was devouring a micro bikini. Bradley? For some reason he was playing tennis.

Julia Roberts said it best ... big mistake, Bradley. Huge.
