Stars In Heat

The 33-year-old smokin' hot bombshell showed off her perfect Polish lady parts in an environmentally friendly green bikini.

Joanna is really wrapped up in her man.

Pop "singer" Ke$ha showed off all of her lovely bones in Australia this weekend ... by wearing a momtastic black one piece swimsuit with an image of a skeleton on it.

That is all.

From the front, 32-year-old super model Gisele Bundchen is pregnant with hubby Tom Brady's baby.

From the back, you'd never know.

This is Nicole Trunfio ... and she's the only famous person we could find today who's in a bikini.

In case you don't know who she is ... Nicole is an Australian-born fashion model who's worked for Victoria's Secret, Chanel, Vogue ... you get the idea.

We really didn't know who she was either ... so we went to her website ... and were greeted with a video that contains partial nudity.

So, if you don't like partial nudity, you should definitely NOT go to her website ... NicoleTrunfio.net.

Another member of Hollywood royalty has gone two pieces.

Mario Lopez's 2-week wife Ali Landry is an expert on her knees, easily keeping her balance during a smoking hot paddle boarding session in Hawaii earlier today.

In case you forgot, Mario and Ali were married on April 24th, 2004. Their marriage was annulled two weeks later.

Call him Ass Ventura.

Jim Carrey hit the beach in Malibu this weekend with a brand new thongtastic bikini chick ... just a short time after reportedly breaking things off with his last GF -- 23-year-old Anastasia Vitkina.

The 27-year-old mother of one is very, very good for the environment.

The 64-year-old Aerosmith front man is so enamored with the silky slacks that he was spotted still wearing them the very next day.

Unlike the bloodless vampire she plays on screen, 24-year-old "Twilight" star Nikki Reed showed off her sexy tan in Hawaii this weekend ... wearing a smoking hot bikini while on a stroll with her husband.

(Fun fact: Nikki's husband is former "American Idol" contestant Paul McDonald, who placed 8th on Season 10.)

After shedding his baby weight in the last few years, former "Drake and Josh" star Josh Peck showed off his worked out svelte physique on the beach in Hawaii this weekend.

Josh is definitely enjoying his moment in the sun.

The former NFL star was actually chillin in the Caribbean with his smokin' hot fiancée, Nicole Murphy, when he got the phone call of the decade ... that he was chosen to join Kelly Ripa as her new co-host.

Sources close to the show tell us, Strahan was through the roof excited when he found out the stellar news and it made his Jamaican get-away that much better.

We're told he and his fiancée celebrated the gig by simply relaxing on the beach and taking in the amazing sites.
