Stars In Heat

Janet Jackson enjoyed soaking up the warm Italian sun on a yacht yesterday ... by laying out fully dressed in black long sleeves, pants and a top hat.

With her Slash impersonation in full effect, the 46-year-old pop icon takes the concept of a beach cover-up to a new level.

Former child star Dakota Fanning,18, and Mary-Kate & Ashley's little sister Elizabeth Olsen, 23, went two pieces on the set of their new movie "Very Good Girls" in New York over the weekend.

In the flick, the bikini-clad actresses play friends who make a pact to lose their virginity during the summer after graduating high school.

There's a damn good chance Terrell Owens will be sentenced to JAIL if he once again blows off his child support hearing in Atlanta on Thursday ... but T.O. didn't seem to care this weekend because there was a BEACH PARTY in Malibu!!

Smiling like he wasn't $20k behind in child support payments, Owens took off his shirt and posed up with "Dancing with the Stars" pro Derek Hough and "Extra" host Maria Menounos at the Chapstick Beach House.

Just a few days before the party, Owens got himself into some hot water with an ATL judge after no-showing at a child support hearing. Owens allegedly owes $20k in back payments to the mother of his 7-year-old daughter.

Terrell's lawyer took responsibility for his client's no-show -- blaming it on a simple miscommunication. But according to reports, the judge was PISSED and has threatened to lock up the former NFL star if he misses the next hearing, scheduled for Thursday July 19.

NIce abs tho.

Now that his ex-girlfriend Myla Sinanaj says she's 100% not pregnant with his spawn, Kris Humphries celebrated by partying shirtless in South Beach this weekend.

Eva was out on the surf with some guys from her new reality dating series "Ready for Love."

"Modern Family" hot mama Sofia Vergara celebrated her big 40th birthday on Tuesday by rocking a sexy bikini in Mexico ... and flashing what is reportedly her new giant engagement ring.

Sofia's on-again-off-again businessman boyfriend Nick Loeb reportedly popped the question this week and gave her the huge bling during their vacation with pals on the Riviera Maya.

Sofia -- who dated Tom Cruise back in 2005, before the whole Katie Holmes thing -- has a son from a previous marriage.

Jessica Alba let all her bronzed gorgeousness hang out in a sexy two-piece bikini while soaking up the sun in Italy on Tuesday.

Just like Scarlett Johansson, the 31-year-old mother of two can definitely stomach the European heat.

It's no secret what Scarlett Johansson's super powers are ... looking ridiculously hot in a sexy wet bikini.

The 27-year-old showed off her Black Widow curves while on a yacht in Italy with a super buff man friend on Monday.

Kate Hudson took a holiday from making all those awful romcoms to bask her mother-of-two curves in a sexy black bikini in Greece on Thursday.

Despite "Alex and Emma," "Raising Helen," "You, Me and Dupree," "Fool's Gold," "My Best Friend's Girl," "A Little Bit of Heaven" and "Something Borrowed," the fit 33-year-old has a great body of work.

And now ... some photos of Hayden Panettiere in a really small, wedge-tastic bikini ... because it's summer.

Hayden hit the beach in Cabo San Lucas, Mexico this week ... showing off her tiny physique as she tanned by the pool.

Seal's officially done mourning the death of his marriage to Heidi Klum ... 'cause the singer has moved on to a smokin' hot brunette who looks damn good in a bikini ... and TMZ has the pics.

Just 3 months after Heidi filed for divorce, an extra-sweaty Seal was spotted on a yacht in Italy this week ... gettin' all kissy kissy with a mystery babe after a quick workout session on the deck.

There was cuddling ... there was smiling ... but there was no sign of Seal's wedding ring.

TMZ broke the story, Heidi decided to break off the marriage because she got sick of Seal's explosive temper. The couple later released a joint statement saying they had simply "grown apart."

Meanwhile, Heidi ain't lookin' so bad either ... and made sure the world knew it on July 4th ... when she tweeted out this photo of her insane supermodel physique.

Damn.

She ridonkadonkulous!

Victoria's Secret supermodel Candice Swanepoel is used to walking around in her underwear ... and basically did that by wearing a ridiculously sexy mismatched tiny two piece swimsuit in Miami Beach on Wednesday.

Ladies and gentlemen, it's that time of year ... when Leonardo DiCaprio trots out his super-hot bikini-clad supermodel girlfriend and reminds you that it does not suck to be him.

This time, Leo was out in Hawaii with his 23-year-old Victoria's Secret model plaything Erin Heatherton (33-24½-34).

Leo's pal Tobey Maguire was also hanging out on the beach.

Just to remind you -- before Erin, Leo was romantically linked to Gisele, Bar Refaeli, model Kristen Zang, model Emma Miller, Blake Lively and probably more hot chicks we've never even heard about.

While bronzing his already golden muscled skin on a yacht in St. Tropez on Monday, soccer stud Cristiano Ronaldo had more important things to do than pay attention to his ridiculously hot bikini clad girlfriend Irina Shayk ... like take a nap.

62-year-old super rich former Formula One manager Flavio Briatore -- who is the biological father of Heidi Klum's eldest daughter -- enjoyed the sight of his 32-year-old bikini-clad model wife Elisabetta Gregoraci in Sardinia, Italy the other day.

Who says money can't buy you happiness?
