Stars In Heat

Here's international supermodel Irina Shayk ... showing off her INSANE physique during a beach trip in Cancun, Mexico.

The 29-year-old's bikini top battled heroically to stay in position as Irina splashed around in the surf ... and while there were several close calls ... it ultimately emerged victorious.

Of course, Shayk recently broke things off with her longtime soccer superstar boyfriend Cristiano Ronaldo -- who's gotta be kicking himself right now ... or banging someone else.

Jessica Alba continued to do what she does best Thursday in St. Barts ... rock a bikini better than pretty much anyone.

Cody Simpson is a robot ... or he's the biggest friggin' Knicks fan in the world, because not even a stone cold 10 like Gigi Hadid could break his steely gaze from the game.

Cody lived every dude's dream Wednesday night at Madison Square Garden ... courtside seats and a supermodel pawing at you like you're her first meal in weeks. Yet, all the Aussie singer cared about was watching the hapless Knicks lose to the Nets.

Here's a version of Rob Lowe we can all get behind ... the selfie-taking one who hangs on the beach in Maui with his wife, Sheryl.

Let's face it, being like any version of Rob Lowe would be a good thing for the rest of us.

Roughly 1,000 of the hottest chicks in Texas went down to Houston this weekend ... to try out for a spot on the Texans cheerleading squad ... and TMZ Sports has pics from the smokin' hot audition.

There are 35 spots on the squad -- and EVERYONE needs to tryout ... including members of last year's team.

Right now, we're told the team has cut the roster down to 50 ... with final cuts coming in the next few days.

Michael Strahan has hooked up again ... and showed off his pretty chick in St. Barts.

The athlete/commentator/talk show host/rich person was ready to flaunt his relationship while vacationing with 2 other couples -- including fellow ex-NFLer Tony Gonzalez and his wife.

It seems the stories that surfaced months ago he and Nicole Murphy might get back together ... are ancient history.

As for the lucky chick -- we're told she's not just a vacay hookup. She and Michael have been dating for a few months.

Michael -- who's co-starring in "Magic Mike XXL" -- may have retired from football, but no one told his body.

A Maui beach was blanketed by Eddie Murphy's smoking hot chicks this week -- one of them was his girlfriend, but the others were his daughter and the daughter's friend.

Eddie's gorgeous 35-year-old Australian girlfriend Paige Butcher was there with his 25-year-old daughter Bria and one of Bria's friends. Murphy apparently missed out on the fun.

Get your popcorn ready -- 'cause Terrell Owens got thiiis close to naked for a revealing new photo shoot with celeb photog Tyler Shields ... and TMZ Sports has the pics.

The 41-year-old ex-NFL star spoofed one of his most famous on-the-field moments ... the infamous popcorn incident ... for Tyler's upcoming book "Provocateur," which is set to be released next year.

We're told there will be a BUNCH of huge stars featured in the book -- including Emma Roberts, Rumer Willis and Jennifer Morrison.

Jessica Alba still does spring break like she's 23, and she's got the booty to back it up -- as she proved on a Caribbean beach with Chrissy Teigen.

Jessica, Chrissy and John Legend were frolicking in the water Thursday -- and it's almost like Alba's ass knew it had to do something to stand out with so many celebs in one spot.

Mission accomplished.

Not to be a buzz kill, but Jessica's 3-year-old daughter Haven is in the photo too (pink hat).

Sorry. You may now resume objectifying her mom -- and because we have a deep respect for history ... here's a classic.

"Millionaire Matchmaker" star Candace Smith made the perfect love connection on an L.A. beach Tuesday ... between her ass and the paparazzi.

Candace -- a former beauty queen -- hit the sand for some volleyball and a pigskin toss (looks like she has game) ... with her pal ex-Miss USA Susie Castillo.

Like all finely tuned athletes ... Candace knows nothing's more important than stretching. Well, that and a very small bikini.

Here's Hilary Duff ... showing off what Mike Comrie will be missing out on now that she's decided to pull the plug on her marriage to the former hockey star.

Duff posted the pic to her Instagram account ... with the caption, "Hey #moms #westillgotit ❤️ #loveyourbod."

Duff and Comrie separated in January 2013 ... but she finally filed for divorce back in February.

Britney Spears is a 33-year-old mother of two, while Gigi Hadid is a 19-year-old model -- and there's no better proof of that than these pics of how they hung out with their significant others.

Brit took her boyfriend Charlie Ebersol to see her son Jayden play soccer in Los Angeles. Meanwhile in Miami Beach, Gigi threw on a two-piece and frolicked around in the ocean with her man, Cody Simpson.

It's 48 degrees and cloudy in Detroit ... so Matt Stafford's future wife hit Vegas for her bachelorette party -- and proved her ass can hang with the best of 'em!!!

Kelly Hall and her gal pals hit the pool party at Wet Republic at the MGM Grand ... where she did some bikini crowdsurfing ... bikini cheerleading ... and other bikini-clad activities -- under the 85 degree Vegas sun.

The Detroit Lions quarterback and his college sweetheart got engaged last year ... and they famously broke the news at a Cold Stone Creamery.

Now, the wedding is right around the corner -- hopefully, the reception will be half as much fun a the bachelorette party!!

Kellan Lutz celebrated his 30th birthday Saturday night with a flair ... at Dan Bilzerian's Hollywood Hills pad.

There were hot naked chicks and dudes wearing very little, per the invitation, which says, "The pool is heated to 95 degrees, and the Jacuzzi is on! We bought 150 white towels, and encourage everyone to bring a bathing suit (white bathing suit preferred)."

Everything was white. The invite makes it clear it's "an all white party. You will not get in if you are not wearing all white."

Kate Hudson was hanging at the beach Saturday with Chris Martin ... which is interesting, right?

Kate split from hubby Matthew Bellamy in December, and Chris has parted ways with Gwyneth Paltrow and moved on to Jennifer Lawrence. So the fun-in-the-sun day in Malibu is kinda curious.

Kate and Chris both brought their kids along, and they've been friends for a long time, but it's still interesting, right?

If this is how Carl's Jr. babe Charlotte McKinney plans to rehearse for her upcoming gig on "Dancing With the Stars" -- there's at least a chance we might be interested in that show again.

Hint for the 'DWTS' wardrobe department -- save the bikinis for Charlotte, and keep them away from Redfoo ... at all costs.

Of course, it's easier (and hotter) to just watch her burger spot instead.
