Stars In Heat

Khloe and Kim Kardashian were in a horse race Friday night ... each clearly trying to take the evening with assets that are undeniably spectacular.

Khloe and French Montana got nice and cuddly sailing on the Utopia III in NYC on the Hudson River ... to celebrate K.K.'s 30th birthday ... and her incredible ass clearly made some partiers go full mast.

And then there's Kim ... whose boobs could save perhaps a dozen lives in a nautical emergency.

Oh yeah ...Kris, Kylie and Kendall Jenner were there too.

Now that's a party we could get behind.

Michelle Rodriguez can really take a lickin' ... because she threw her body around like a circus performer ... diving, flipping and romping around on a yacht in Italy, but her bikini clung to her body tighter than Cara Delevingne ever did.

Chrissy Teigen must not have wanted her bra to set off any security alarms at the airport, that’s the only reason we can think of why she left it at home!

We could explain to you in detail what her boobs look like with no bra, in a see-through white shirt, swinging their way through LAX ... but it’s better if you just watch it yourself. Trust us.

The transsexual woman who allegedly had an affair with Hank Baskett is threatening to sue a magazine company she claims is spreading lies about their alleged encounter.

As TMZ first reported, Ava London claims In Touch and Life & Style lied when they said they interviewed her and their reporters harassed her to the point she had to call the cops.

Now London's lawyer has fired off a cease and desist letter to Bauer Media, writing, "You must be delusional ... You must be living in a land of strawberry fields where nothing is real and nothing to get hung about."

London wants the stories in question removed from the Internet. She also says if the mags continue to write these stories ... she'll sue.

The bad news for Baskett ... London acknowledges she did give an interview to another outlet in which she claimed to have hooked up with Baskett. She says the two of them simply engaged in a little fun with their hands, nothing more.

Courteney Cox just turned 50.

Anna Faith Carlson, the smoking hot model who bares a strong resemblance to Elsa from "Frozen," was spotted out on the beach in Florida this week ... with a body that is anything but G-rated.

She's clearly not let herself go.

Professor Lasky from "Saved the Bell: The College Years" says he's offended Lifetime producers haven't called him for a cameo in the new 'SBTB' flick -- even though the movie isn't about him.

Patrick Fabian a.k.a. Lasky a.k.a. the teacher who banged Kelly Kapowski ... was at an event in East L.A. Saturday -- when he started fishing for a cameo in the new TV biopic about the show.

In fact, Fabian even has an idea in mind for how producers could make it work.

Jennifer Lopez and Maksim Chmerkovskiy say they're just friends, but they could smell each others pheromones judging from this pic ... obtained by TMZ.

JLo and Maksim were at the Foxwoods Casino in Connecticut Saturday night after her show. They hit up the Shrine nightclub and were certainly close.

They say they're just friends with a common interest ... dancing. Interesting ... she said on a TV show recently that dancers were better in the sack than actors. It's a compliment to Maksim and a diss to you know who.

There musta been storm clouds following Floyd Mayweather this weekend ... 'cause dude made it rain HARD in a Miami strip club ... throwing around $100k in cash ... and TMZ Sports has the footage.

Mayweather rolled into E11even to celebrate DJ Irie's birthday -- with a backpack that we're told contained $100k in greenbacks (Floyd was showing off some of the cash on his Instagram page earlier that day).

Our strip club sources tell us ... Jamie Foxx and Diddy were also in the building -- and at one point Diddy called every stripper down to the floor while the guys threw around fist-fulls of cash.

It's not like it's a big deal to them -- according to Forbes, Diddy is worth around $700 mil ... and Floyd made $105 mil over the past 12 months alone.

It's good to be rich.

Miley Cyrus found something new to stick between her legs during her concert in Amsterdam on Sunday night ... a giant inflatable banana.

Posing with a strategically placed No Entry sign, model Cara Delevingne served up a subtle reminder to the guys which way she goes.

Mercedes "MJ" Javid swears she hasn't been photoshopped, she really did drop 20 lbs., and she tells TMZ ... she did it the old fashioned way -- lots and lots of sex ... and some traditional exercise.

The "Shahs of Sunset" star says she's seen all the haters accusing her of doctoring the pics from a recent swimsuit shoot -- but says her real secret is simply banging the weight away.

Best of all ... MJ claims the more pounds she shed, the more sex she had -- and the more sex she had, the more calories she burned. The least vicious cycle ever!

She admits cutting back on hard partying and late-night boozing definitely helped too ... along with hiking, biking, tennis and dodge ball -- but says she's definitely sticking to her sex diet. She says bluntly, "I'm too pretty to be fat!"

Taylor Lautner hit the beach looking really really ... different? The 'Twilight' stud seems to be about a six-pack shy of the guy we're used to seeing.

But what's most disappointing about Taylor's new physique is -- it's still at least 10 times better than the rest of ours. Damn werewolves!

Justin Bieber caught a few ZZZZZs in the studio last night ... and he did so cuddled all up on Selena Gomez.

This continues the latest reunion of the entity known as Jelena. As TMZ first reported, the two hung out on Monday night at Bootsy Bellows for a friend's birthday ... and Justin recently Instagrammed a photo of them with the caption, "Our love is unconditional."

Our sources say Selena's family is worried about her reconciliation with Bieber and feel it's no coincidence she threw an all-out rager at her house right when she's getting back together with Bieber.

The pic was taken on Shots ... a selfie app.

Shahs of Sunset star, Mercedes "MJ" Javid painted on a bathing suit for a rooftop photo shoot in L.A. this week ... and it looks like she's dropped a bunch of weight. LOOKS like it anyway.

MJ's been pretty open about her weight issues -- and last year claimed she was shedding pounds without really trying. She never revealed a number, but this is pretty strong evidence.

But here's the issue -- this is Hollywood where everything isn't always as it seems.

So ... we gotta ask ...
