Stars In Heat

Rihanna forgot something on the way out of a hotel in Stockholm, Sweden today.

Live your life.

Bar Refaeli had some issues with her bikini riding a little too high up during a yacht trip off the coast of Spain this weekend.

Fortunately, she managed to fix the problem. Here's the proof:

She's twerked on land ... and now Nicki Minaj is twerking at sea -- and fortunately for the human race, she captured the entire aquatic adventure on tape.

A bikini-clad Minaj twerked off inside of a swimming pool -- wearing a skimpy little bikini that accentuated her legendary badonk.

"Modern Family" star Sofia Vergara threw on her whitest bikini in Greece this week ... and flashed a vertical smile to all of the locals.

Sofia seems to be on a butt-flashing kick these days ... as evidenced by this, this, this and this.

God, we love you.

Like a spitting image of The Situation, Justin Bieber once again blew his top ... and flexed his abs HARD for some shirtless photos on a boat in Connecticut.

Complete with soggy sagging basketball shorts and Marky Mark inspired underwear, Bieber hung topside with his posse -- Including Little Za and Twist -- to soak in the sun.

Dude seems to be allergic to shirts these days -- he's been showing more skin than that guy from "Silence of the Lambs."

So, here's a photo of supermodel Bar Refaeli kissing another woman ... you're welcome.

The other chick appears to be Bar's good friend Orna Elovitch. We don't really know much about her ... but she got to go mouth-to-mouth with Bar, so she's clearly important.

Stuff like this almost makes you forget Bar tongue wrestled with the GoDaddy guy ... ALMOST.

So ... when Andy Murray's girlfriend agreed to play the Wimbledon champ in a game of smash ball on the beach this week ... think she felt a tad bit inadequate?

26-year-old Murray and his 25-year-old GF Kim Sears celebrated his big Wimbledon victory with a beach trip to the Bahamas ... and the first order of business -- beach tennis.

Meanwhile, Andy's top Wimbledon opponent, Novak Djokovic, was last seen at a village in Serbia ... riding a tractor.

Murray wins. Again.

Someone needs to tan Joel Osteen's hide ... or at least his chest, because the guy who provides holy inspiration to millions is downright pasty.

Joel was vacationing in Hawaii with his fam ... taking in a little paddle boarding.

The 50-year-old pastor -- who prayed with Nik Wallenda before and after he traversed the Grand Canyon on a highwire last month -- looked pretty fit.

He just needs a little sun to distinguish himself from the Holy Ghost.

Some kayaking lessons wouldn't hurt either, Rev. Just sayin' ...

Here she is ... 2012's hottest woman in the KNOWN UNIVERSE -- at least according to the Miss Universe beauty pageant -- and unless there are some really hot aliens out there, we have to agree.

Representing the Third Rock from the Sun in a sexy mixed-pattern bikini, 21-year-old Olivia Culpo stripped down on a beach in Corona del Mar over the weekend.

Looking like a cross between Coco, Anna Nicole Smith, and two young girls who just got their hair braided on a cheesy summer vacation, Playboy's famous twins Kristina and Karissa Shannon resurfaced in L.A. recently ... or at least their tanned asses did.

Here's Rihanna in a tiny bikini at a beach in Sopot, Poland this weekend ... where a giant pack of Poles lined up behind a fence to gawk.

Rihanna wasn't thrilled with the attention -- actually, she was pretty pissed ... tweeting, "Tried to have a beach day, that was a fail!!"

RiRi later griped that she felt "caged in like a f**king animal!"

Fun Fact: Sopot is a popular spa town for the rich and famous ... and sports the longest wooden pier in Europe.

Heidi Klum just posted this on Twitter ... and we have TWO fun facts:

1) Klum was born in Germany but obtained her American citizenship in 2008.
2) Who cares? She's in a bikini.

NFL stud Eric Decker and country singer Jessie James flaunted their disgustingly perfect bods on their honeymoon ... and staked their (debatable) claim to the title of hottest married celebs.

Seriously ... Ken and Barbie should bury their heads in the sand.

Just days after tying the knot, Denver Broncos star Eric Decker and country singer Jessie James took their talents to Maui ... and DESTROYED everyone else who dared put on a swimsuit.

Seriously, these people are frickin' beautiful.

The couple married back on June 23 in Colorado after a year-long engagement.

Ryan Seacrest looks like a baller in the South of France ... but he's single among 2 extremely hot (and taken) women ... TMZ has learned.

There have been multiple reports linking R.S. to a mystery woman ... the one in the cream-colored lace dress. Here's the thing. Her name is Janelle Hallier. She's hot, married to mega-millionaire businessman Laurence Hallier and they have 2 kids. They're Ryan's best friends, and that's why they're on the boat he chartered in St. Tropez.

Two hot women ... two tiny bikinis ... but you can only CHOOSE ONE!!

First, "Pretty Little Liars" star Lucy Hale -- she's 24, she's in Hawaii, and she's smokin' hot.

Choose wisely.

Bonus Fun Fact -- besides being a huge singer, Milian also co-wrote the Justin Bieber smash hit "Baby." So, take that into consideration.
