Stars In Heat

Lacey Wildd -- the reality TV star who recently underwent her 36th plastic surgery -- squeezed herself into a pink bikini Friday on a beach in Florida.

Wildd is a 46-year-old mother of six (let that sink in) and has had 12 boob jobs alone ... going from an A-cup to the ridiculous LLL-cups she flaunted today.

She's been on TLC's "My Strange Addiction" and is set to appear on the new E! series "Botched."

As far as those shows are concerned, Wildd's a natural.

Justin Bieber clearly has a thing for Australian women ... a day after brawling with Orlando Bloom over Miranda Kerr, Biebs was spotted on a yacht in Ibiza with another Aussie babe, Shanina Shaik.

Shaik -- who Instagrammed a few shots from the boat -- was born and raised in Melbourne and has done modeling work for the likes of Vivienne Westwood and Chanel. She dated Tyson Beckford for years until their breakup in 2013.

There's no evidence Justin was involved with their split, so he should be safe ... which is good. Tyson is waaaaaaaay bigger than Orlando.

Gisele Bundchen frolicked around on the beach Tuesday in Costa Rica ... crawling around in the ocean with her adorable dog Lua.

In search of someone who could help protect him should Orlando Bloom strike again, Justin Bieber hung out Wednesday on a yacht in Ibiza with none other than Michelle Rodriguez.

There's nothing romantic going on here -- at least not in these photos -- and besides ... MRod's been hanging with a completely different skinny and often shirtless guy in Zac Efron.

If it came down to it, we feel pretty confident Rodriguez could take Bloom ... and Bieber ... and even Efron in a fight.

If Orlando Bloom was worried about Miranda Kerr -- hours before fighting Justin Bieber -- he wasn't showing it because he had his hands full with multiple hot chicks.

Bloom was cruising around the island of Ibiza Tuesday on a speedboat, pumping his fists in the air, dancing with beautiful women ... and looking like he's shouting, "Turn Down for What!" Ultimate bachelor's life.

Looking at these pics, it was VERY GOOD to be Orlando yesterday. Last night? Not so much.

Shoulda stayed on the boat, Orlando.

Kate Walsh went to Disneyland, but it's hooters that ended up making her day -- as she cupped a pair of boobs on Splash Mountain.

The "Private Practice" actress kept her hands well inside the log flume over the weekend -- and showed full support for the knockers seated in front of her during the ride's signature drop.

Kate seemed unimpressed with the rack, but maybe she's just felt 'em before. Turns out the chick is a friend of hers.

Caution: Riders may get wet.

Gerard Butler was up to his old tricks this weekend ... engaging in a full-on makeout session outside of Nobu in Malibu Sunday night.

When he finished facesucking the cute brunette in cut-off shorts -- naturally -- they each went their separate ways and Butler rode off alone on his motorcycle.

Paris Hilton and boyfriend River Viiperi are on the outs, cause she was sucking face with some guy on the beach this weekend ... someone other than River.

Hilton and her new male model friend Josh Upshaw were in Malibu Sunday when they got deep into a make out sesh ... right in the open. According to our sources, Paris and River ended their relationship amicably recently.

Neither has spoken about the break-up, but they haven't been seen together for several months now.

The River no longer runs through it.

It's Selena Gomez's birthday, but we're getting the gifts -- behold Selena and Cara Delevingne showering ... together ... in bikinis ... on a yacht.

Our favorite new BFFs made the sexiest pitch for water conservation while continuing SG's bday week celebration in St. Tropez -- but this time they had company in the form of Tommaso "Tommy" Chiabra.

In addition to ruining an otherwise perfect moment ... Chiabra has been seen with Gomez a lot recently, and has also been linked to 'Gossip Girl' Jessica Szohr.

Hate him. Love the pics.

Selena Gomez celebrated her 22nd birthday in St. Tropez with smoking hot model Cara Delevingne -- who famously celebrated … other stuff with Michelle Rodriguez.

Now Cara's got Selena's back. We're undecided about her front … for now.

Notorious friender Cara Delevingne has a new gal pal ... Selena Gomez, who celebrated her 22nd birthday with Delevingne aboard a yacht in St. Tropez.

Forget posing for a pic with model Tanz Watson, if Selena really wants to make Justin Bieber jealous ... this is how you do it.

Coolio is banking on a whole lotta ass making him a player in the music biz again -- he's teamed up with a porn website for his new music video ... and it's filled with wet t-shirts, garden hoses, twerking dinosaurs ... and even Coolio.

Coolio tells TMZ ... Pornhub.com agreed to provide all the "talent" for his video -- "Take it to the Hub" -- and in exchange he's going to debut all his new music on the website.

We're told Coolio and co. banged out the vid in about 5 hours at a house in Sherman Oaks, CA. The video's pretty funny ... for some reason the director had to remind Coolio and the girls, "Smile while you're doing this. Look like you're having a good time."

This is 50-year-old Coolio's first album since 2009.

Best part of the shoot -- featuring Jessica Bangkok, Missy Martinez and Skin Diamond -- the catering was provided by the nearest El Pollo Loco.

Ay, dios mio.

Lea Michele proudly displayed the 3 Bs during her Italian vacay -- boyfriend, boat, and a whole lot of her thong-framed butt.

The "Glee" star was spotted making out with her bf Matthew Paetz ... onboard a boat off Positano this weekend.

Apparently, Matthew's gigolo "research" is paying off -- cause the "coach" is scoring big time on the open sea.

That's amoré!

Whether they are a male or female some stars look good going either way... Check out what celebs like Kate Beckinsale and Joseph Gordon-Levitt would look like this summer if they were given a sex switcharoo!

It's kinda like that movie "The Hot Chick"... but way sexier.

Pam Anderson clearly had a change of heart after filing for divorce earlier this month.

Pam and hubby Rick Salomon were making out in Malibu Wednesday, showing no sign of ending their 6-month marriage. It's their second try at marriage. They married in 2007 ... it lasted 2 months.

As we reported ... Pam listed the date of separation as July 3 ... 2 days after Rick won $.2.8 million in a poker tournament -- which means it would be community property -- split 50/50 (we're told there's no prenup).
