Hot Bodies

While you may only have about a month to get ready for bikini season, some of Hollywood's hottest babes are always ready to go two pieces.

It was a former Disney dude buff arm battle, as "High School Musical" hunk Zac Efron, 25, flashed his tan, ripped muscles before hurting his wrist while filming his new movie in L.A. this week (left) -- while musclebound "Camp Rock" boy bander Joe Jonas, 23, pumped up his God-fearing biceps in a funny new video clip (right).

They've both grown up to be fine young men, so we gotta ask ...

While the New York Yankees got ready to play the Orioles -- injured superstar Alex Rodriguez engaged in his version of spring training today ... lounging poolside with gf Torrie Wilson.

A-Rod's recuperating from major hip surgery, but the 37-year-old is keeping busy -- y'know ... checking Facebook, soaking up the sun and enjoying the sight of Torrie's rock hard bikini bod in Miami ...

How did Halle Berry's pregnant belly go from baby bump to bustin' out in just a few days? It's simple -- popcorn! Umm ... we'll let the little guy who knows zero about birthing babies explain that one.

Ke$ha arrived to "Jimmy Kimmel Live" in Hollywood on Thursday and went almost completely unnoticed ... because she looked frickin' amazing.

Rockin' her best Shakira drag, the reupholstered 26-year-old alleged singer defied all odds by standing upright and showing off her newly fumigated blonde weave, purified skin and gorgeous toned legs last night.

Just like a batch of gorgeous Jiffy Pop popcorn, mom-to-be Halle Berry's baby bump is blowin' up.

While barely showing any overt signs during the last few weeks, the beautiful three-plus months preggers 46-year-old heated up the premiere of her latest bomb, "The Call", in Rio on Thursday ... and showed off her suddenly huge Halle belly.

With all that "Les Miserables" garbage thankfully behind him, Hugh Jackman got back to doing what he does best ... working on his ridiculously buff bod at a NYC gym yesterday.

The diesel 44-year-old even stopped to strike a Wolverine pose in between sets of pumping iron.

Kim Kardashian gets almost as many headlines as that other Kim -- so, we're thinking Kim Jong Un should just get knocked up by a rapper. Beats launching World War III ... just sayin'.

Bogus sex tape peddler Farrah Abraham just can't hide it anymore ... her breasts that is.

Abraham went frolicking on an L.A. beach earlier today in a barely-there bikini, where she celebrated the imminent release of her totally-staged "sex tape" with porn star James Deen.

TMZ broke the story ... Deen blew the lid off Farrah's sex tape plot yesterday ... telling us he was approached by a porn company to stage the sex tape over the weekend ... and that Farrah was behind the whole thing.

And we're not complaining ... at all.

Katherine Heigl took time out from making horrible romantic comedies and showed off two gorgeous reasons why she should still be cast in more films.

The 34-year-old former television actress poured herself into a golden yellow bikini top to tan her blockbuster lady curves in Cabo on Monday.

As long as it doesn't mean any sequels to "27 Dresses," "The Ugly Truth," "Killers," "Life As We Know It," "New Year's Eve," or "One for the Money," we'd all love to see more of Kat.

Rockin' a 1993 "Melrose Place" choker and a pair of tattered jean shorts, sometime actress Mischa Barton went for a leisurely stroll in Los Angeles on Monday.

It's been ten years since "The O.C." premiered and the fresh-faced 27-year-old "A Resurrection" star has proven her career still has legs.

Contrary to popular belief, Marissa Cooper is alive and well.

It's baby bump's first red carpet ... as a glowing, newly pregnant Halle Berry showed off her growing belly -- and sexy legs -- at the premiere of her new movie "The Call" in Buenos Aires on Monday.

As TMZ first reported, the 46-year-old is three months pregnant with her first child with fiance Olivier Martinez and has learned she is having a boy. Halle already has adorable 5-year-old Nahla from her previous relationship with Gabriel Aubry.

Don't cry for her Argentina ... well, unless you go see "The Call."

Chris Bosh's wife Adrienne hit a Caribbean beach with their adorable 11-month-old son -- who was udderly overshadowed by his mom's booty-FILLED bikini.

Mary J. Blige isn't letting a little thing like financial ruin stop her from vacationing in the Caribbean.

Rockin' a sexy green bikini, the 42-year-old cash-strapped R&B diva tried to get her mind off the $900K tax lien she got hit with in February ... and defaulting on a $2 million bank loan last year ... and the $250K bank loan her charity was sued for ... by somehow finding the means to jet down to Puerto not-so Rico this weekend.

All that drama has Mary feeling the heat.

2:35 PM PT -- A rep for Mary tells us the singer, "was performing at an event, she was NOT vacationing."

Miami Heat star Chris Bosh may have had over $300K in watches and rings jacked from his home, but he's still got the family jewels ... his wife's bootyful bikini body.

Looking like a long lost Kardashian, Adrienne Bosh barely contained herself in a red two-piece as she showed off her buxom precious gems on the beach with her son in Puerto Rico this weekend.

She's making those crooks look like a giant ass.
