Models

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.

Gigi Hadid's patriotic outfit is a smoking reminder that EVERY day should be the 4th of July.

Gigi modeled the hell out of a red and white striped swimsuit Thursday in L.A. for a Tommy Hilfiger photo shoot.

New England Patriots star Julian Edelman may have pulled a Tom Brady ... allegedly knocking up a smokin' hot lady ... and then moving on to date a world-famous supermodel.

Lydia Hearst's bachelorette party was a perfect fit for her last name -- no cheesy Vegas strip club, instead her turn up went down inside historic Hearst Castle.

Sources close to Lydia -- who's engaged to TV host Chris Hardwick -- say she took 18 friends to the San Simeon, CA landmark built by her great-grandfather ... newspaper magnate William Randolph Hearst.

Her guests included Cara Santana, Michelle Trachtenberg, Clare Grant (Seth Green's wife) and actress Jillian Murray. The ladies were treated to a 2-hour VIP tour ... complete with a swim session in the famed indoor Roman pool (usually off limits). The floaties were pre-approved.

We're told private events at Hearst Castle typically cost up to $22,000 ... but with the family discount Lydia's tab came to $0.00.

Perks of royalty.

Here's supermodel Gigi Hadid ... proving she's one hell of an athlete -- by hitting a heavy bag -- IN HEELS!!!

Hadid hit up Gleason's Gym in Brooklyn -- and despite the fact she was wearing (what appeared to be) leather leggings and chunky heels ... she went all Rocky Balboa anyway -- and looked damn good.

Gigi's been boxing for a while -- and she's picked up a pretty solid overhand right.

#Respect.

Alessandra Ambrosio's on an endless yacht vacation that just gets better and better ... courtesy of her smoking hot friends, including Sofia Richie.

Lionel's model daughter is hanging with Alessandra and co. off the coast of Ibiza. They've been going cray cray on vacay -- holding hands leaping into the water, dancing with each other ... and showering on deck. Lots of showering.

Another New England Patriots star ... dating ANOTHER smokin' hot supermodel.

This time, it's wide receiver Julian Edelman and Victoria's Secret Angel Adriana Lima.

Listen up, Christian McCaffrey ... a (smoking hot) modeling vet has some advice for you ... STICK TO FOOTBALL ... saying there's waaaaay more money in catching passes than catwalks.

We got former SI Swimsuit model Genevieve Morton out in L.A. and asked her professional opinion of Christian's shirtless look ... the one that's been driving the ladies (and some fellas) crazy all week.

The thirst fest has been so rampant that it's made some people wonder if Christian has a future off the gridiron as the next big thing in the modeling world.

Check out the clip -- Genevieve thinks that's a BAD IDEA ... telling our guy that Christian could definitely model if he wanted to ... but he needs to keep his (hot) ass on the field if he wants to make big cash.

BTW ... Christian, if you're reading this she seems totally down ... might be worth a DM ... just sayin'.

Carl's Jr. knows how to sell it, and they've done it again with 3 super hot models diving into the same burger at the same time.

We got pics from the latest C.J. offering ... a Bacon 3-Way Burger ... loaded with thick cut, Applewood-smoked bacon strips, crumbled bacon and bacon jam. The bacon booty sits atop a patty weighing in at 1/3 of a lb.

Genevieve Morton -- the one in the photo with the burger -- was out and about in L.A. Thursday when our photog asked what we all wanted to know ... how much burger-munching on the set? She even shows us how it's done!

From babe ... to babes.

Dani Mathers -- the Playboy Playmate who took a picture of a naked woman in an L.A. gym -- has hired no less than the famous lawyer who got Michael Jackson acquitted ... and she has reason for worry.

We've learned Mathers hired Tom Mesereau, who not only got MJ off ... he won a murder acquittal for Robert Blake.

TMZ broke the story, the LAPD launched a criminal investigation after the gym where the photo was taken filed a police report. Mathers not only snapped the pic in the locker area, she shamed the woman by writing a snarky caption and posting it on social media.

Our LAPD sources say they are on the hunt for the victim and are working closely with LA Fitness execs, combing over surveillance video and checking member swipes during the time in question to ID the victim. And, we're told, they're close.

Our sources say the LAPD would like to present a criminal case to the L.A. City Attorney but need the cooperation of the victim.

Former Victoria's Secret angel Doutzen Kroes joined the yacht party that could totally pass for a runway fashion show.

The Netherlands native hopped on the same yacht in St. Tropez where we've seen Alessandra Ambrosio, Joan Smalls, Lily Donaldson and Constance Jablonski ... soaking up the sun and getting very wet.

It's not often that supermodel Alessandra Ambrosio is just another chick in the crowd -- but it's also not often she's on a yacht packed with Victoria's Secret models. Yes, dreams do come true!

Joan Smalls, Lily Donaldson, Constance Jablonski -- who've all walked the VS runway -- were there too. So was Nicole Richie's little sister, Sofia.

Two Wilhelmina models got down and dirty ... which would explain the wet t-shirts.

Ashley Robbins and Nereyda Bird flaunted their stuff Tuesday during a Miami photo shoot.

Kendra Wilkinson is NOT standing shoulder to shoulder with fellow Playmate alum Dani Mathers -- in fact, she's going off on her for the despicable gym sauna pic.

We caught up with Kendra at LAX and she didn't mince words about the former Playmate of the Year. Check out the vid ... she's clearly pissed at Dani for mocking an unwitting woman.

She's also got beef with anyone trying to drag Playboy into Dani's mess.

Miranda Kerr looks like a billion bucks ... and not because she's dating the guy who founded Snapchat.

Miranda was earning her own money Monday in Malibu during a pretty hot photo shoot.

Model Chantel Jeffries hung a rainbow over South Beach ... and we're betting more than a few leprechauns were chasing it too.

Justin Bieber's ex-gf/travel pal is still leading a very colorful life -- even without the pop star.
