Hot Bodies

Justin Bieber shocked a gym full of people yesterday -- not with his basketball skills, but by keeping his shirt ON while he was balling.

Going topless has kinda become JB's trademark, yet he hit the hardwood at Equinox in West L.A. for a pickup game with his buds ... and actually wore a black tank (and headband) while playing.

Justin didn't totally disappoint though. Check out our hot, sweaty footage of him leaving the gym.

Shahs of Sunset star, Mercedes "MJ" Javid painted on a bathing suit for a rooftop photo shoot in L.A. this week ... and it looks like she's dropped a bunch of weight. LOOKS like it anyway.

MJ's been pretty open about her weight issues -- and last year claimed she was shedding pounds without really trying. She never revealed a number, but this is pretty strong evidence.

But here's the issue -- this is Hollywood where everything isn't always as it seems.

So ... we gotta ask ...

Taylor Lautner hit the beach in Los Angeles this week while filming his new movie ... but he appears to have left his abs back in Forks, Washington.

Smoke show Ana Braga hit the beach in Miami, proving there is at least one Brazilian on the planet NOT obsessed with the World Cup.

The bikini model who was once featured on the cover of Playboy Venezuela ... supported her futbol team Tuesday -- the same day they played Mexico -- by wearing a super teeny tiny g-string bikini.

Considering the Mexico match ended in a 0-0 tie ... Ana might need to wear even less for Brazil's next game.

Former Playboy playmates Karissa and Kristina Shannon frolicked on the beach in the Pacific Palisades yesterday with some unusual beach accessories ... burgers and fries.

Hef's ex-girlfriends enjoyed an afternoon at Will Rogers Beach with a few Big Macs and a couple orders of fries. The girls have done a ton of growing up -- all over -- since their Playboy days in 2009.

It may seem odd to bring fast food to the beach, but who doesn't love a set of juicy buns?

With their equally legendary backsides already enshrined in the Hall of Fame, Kim Kardashian and Jennifer Lopez each wore outfits on Monday that showed off their commonly overshadowed cleavage.

First we have Kim (left) in New York City after having dinner with her sister Kourtney, and then J.Lo (right) appearing on 'The Tonight Show.'

The question is ...

According to reports ... Kanye stuck to his normal schtick during the gig -- ranting about how he wants to become a timeless icon like Walt Disney and Shakespeare.

The entire TMZ Sports newsroom just became fans of Team Mexico ... because every time the squad scores a goal, Playboy's 2013 Playmate of the Year is celebrating by bouncing around in a skimpy top.

Raquel Pomplun -- who was raised in Tijuana -- is live-cheering the game with Playboy and Hornitos tequila ... which basically means she quickly records a sexy video anytime Mexico does anything noteworthy.

Earlier today, Mexico scored its first goal of the World Cup against Cameroon ... and Pomplun went wild.

No one at the Maxim Hot 100 party had their conversations secretly recorded last night ... that's because V. Stiviano was TURNED AWAY at the door ... TMZ has learned.

According to our sources, Stiviano showed up to the Pacific Design Center looking to get in ... but she wasn't on the list. We're told Stiviano tried her best and put up a bit of a fight ... but ultimately she was persona non grata.

Candice Swanepoel arrived at the Maxim Hot 100 party in Los Angeles last night ... and quickly reminded us why she's #1 this year. Good luck knocking this off the throne next year.

Bow down.

Ryan Phillippe is suddenly looking JACKED on South Beach, and you can bet he's getting a ton of stares from the ladies -- and also possibly some gentlemen.

But only because he's their "th-inspiration." Yep, that's the only reason.

Joseph Gordon-Levitt hammed it up outside his trailer during a break from shooting his latest movie in Montreal.

Will Smith and Jada Pinkett Smith took their tight, toned bodies to the beach today in Hawaii -- proving once again ... Jada is the hottest 42-year-old mom in a 2-piece.

Mr. & Mrs. Smith had something for everyone -- her toned ass barely covered in a bikini ... and his ripped arms in a tank top.

If you're impressed -- you're not alone. 13-year-old Willow was there too ... and looked pretty awestruck by her parents' ridiculous physiques.

Will still rules in Summertime.

Miss USA 2014 is a total knockout.

Turns out 24-year-old Nia Sanchez -- who won the title over the weekend -- can put you in a coma if you cross the line uninvited ... cause she has a fourth-degree black belt in tae kwon do (see below).

During the competition, Sanchez brought up her martial arts training twice during interviews, which she began practicing when she was 8.

Sparring partners ... take a number.

Mel Gibson was all smiles at UFC Fight Night 42 ... flanked by some pretty hot ring girls.

Gibson was front and center for the Henderson/Khabilov main card in Albuquerque. Mel hung out with some of the fighters, include Clay Guida and Cub Swanson.

With his criminal record expunged in the whole Oksana Grigorieva thing ... Mel seems care-free.
