Hook Ups

15-year-old Kylie Jenner is playing the field -- just a week after hitting up a movie with Will Smith's son Jaden, things got SO HOT between her and Justin Bieber's friend Lil Twist ... they had to cool off with frozen yogurt.

While Jaden was out doing his own thing, Kylie and Twist got together yesterday in West Hollywood for some Pinkberry ... A WELL-KNOWN APHRODISIAC!!!

Somebody call Maury ... because Flo Rida underwent a paternity test to determine if he's the daddy of a 2-year-old boy in Florida -- and according to the documentation, he's free and clear.

TMZ broke the story ... Flo Rida was sued for child support in Florida by a woman named Gloria Holloway, who insists Flo fathered her kid.

Flo -- real name Tramar Dillard -- adamantly denied paternity ... and now he's got proof in the form of a DNA test.

TMZ has obtained the doc ... and according to the paperwork, there is a 0% chance that Flo is the daddy.

Sources close to the rapper tell us, his attorneys will be filing the DNA test results with the Florida Department of Revenue to block Holloway from obtaining a child support order against him.

Flo's lawyer tells us, "Flo Rida is absolutely not the father of the child and does not expect to hear anything else on the subject." Calls to Holloway weren't returned.

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.

The woman accusing 50 Cent of domestic violence is NOT Shaniqua Tompkins -- the mother of the rapper's 16-year-old son -- it's ANOTHER baby mama, TMZ has learned.

We broke the story ... cops say the victim of the domestic violence incident is a former girlfriend who has a child with 50.

50 has never publicly acknowledged having a second child ... but it appears the woman behind the allegation is Daphne Joy -- a model who famously dated 50 for 3 years.

There were rumors the two had a child last fall ... but neither 50 nor Daphne ever confirmed the birth. In fact, the L.A. City Attorney seemed to break the news in its statement to the media when it said the victim and 50 had a "child in common."

We spoke with Shaniqua, who swore she wasn't the accuser -- and we know Daphne lives in Toluca Lake, where the alleged incident took place.

So ... congrats???

Calls to 50 have not been returned.

NBA legend Michael Jordan tried to win entrance into Kennedy's vagina during a steamy dice game back in 1995 ... so says the former MTV star, who claims she was a virgin at the time.

Kennedy -- who was a huge MTV VJ back in the '90s -- details the encounter in her new book "The Kennedy Chronicles" ... explaining how she was having dinner with MJ and Russell Simmons at the Bowery Bar in NYC, when Michael broke out some dice.

Before long, Kennedy says, Jordan decided it was "time to play for something" ... and said, "If I win, you come back to my hotel room with me tonight."

Kennedy says she freaked out because she was a virgin --and imagined MJ's giant penis would "eviscerate me from the inside out" ... so she asked if they could play for Knicks tickets instead.

And that's when Jordan allegedly reminded Kennedy he had a wife -- and offered her Nets tickets as a consolation.

"Sure, he'll filet my vag like a sea bass if he won at dice on a men's room floor," Kennedy writes ... "but as soon as I want basketball tickets he's a Promise Keeper? Whatevs."

Kennedy says she won the dice game anyway -- so her vag was never in any real danger.

We reached out to MJ for comment -- so far, no word back.

Malibu has become Temptation Island ... because we've learned 17-year-old Kendall Jenner and her 15-year-old sister Kylie Jenner have set up a house by the sea -- where clothes are kept to a bare minimum.

Sources close to the Jenner sisters tell us, the Kardashian fam is renting a palatial beach pad primarily for the two girls during the summer months -- and no doubt, the hormones are going nuts.

You'll recall, Kylie is currently dating Will Smith's son Jaden ... and Kendall's obviously got her own endless list of suitors.

The supposed blackmail first surfaced last night when Miley posted a bizarre tweet to Billy Ray Cyrus -- the tweet contained a picture of a mystery woman along with the caption, "Since you won't reply to my texts I'm giving you an hour to tell the truth or ill tell it for you."

Given the relationship drama between Billy Ray and his wife Tish, we're assuming Miley is suggesting the mystery woman is somehow involved.

Miley has since deleted the post.

FYI -- an "hour" came and went and Miley never followed through on her threat ... unless Billy Ray actually contacted her.

We reached out to Miley's people for comment -- so far, no word back.

We now know why Chris Brown kept the silky panties some chick handed him​ while performing on stage Saturday -- the chick is SUPER HOT, and her panties came unused ... but sweaty.

TMZ has learned the undies tosser is 21-year-old Carol Quiroz -- and she tells us she's such a HUGE CB fan ... she had to make her presence known at the Anaheim show Saturday night.

Carol says her plan was simple ... "I wrote my name, number and Instagram on the thong in permanent marker. I got his attention and handed it to him."

Groupie 101.

Carol also cleared up the most important detail -- the panties were NOT used, but she admits she was holding on to them in her bra. "I definitely had boob sweat on the panties."

For the record ... Carol says Chris hasn't contacted her. Yet.

Justin Bieber tried to impress his Miami mystery date by taking her to Game 7 between the San Antonio Spurs and Miami Heat -- but based on some pics he screwed it up.

It's unclear if things are serious with this new chick -- who seems older than Selena Gomez, and is definitely WAY more endowed!

JB was spotted around Miami with her before the game ... and sitting next to each other in a luxury box during.

Here's the thing ... if Justin really wanted to impress her, he wouldn't have worn those neon sneakers.

We now know what in the Hell Kate Upton was doing hanging out with "Dancing With the Stars" dude Maksim Chmerkovskiy -- and we're still not happy about it.

As we previously (and jealously) reported ... Maks and Kate were spotted leaving a restaurant together in NYC last week.

So, of course we've been wondering how someone known as the "bad boy of the ballroom" ... managed to bag the hottest chick on the planet.

Well, we ran into Maks at LAX, sans Kate, and asked if they're, y'know ... banging?

Charlie Sheen won't be banging Farrah Abraham any time soon -- at least that's what he says. Lots of stars had lots of strife this week, so we gotta ask ...

The ladies LOOOOVE Patrick Schwarzenegger's body ... especially his nipple?

Arnold's 19-year-old kid was hanging out on a yacht in Saint Tropez with his girlfriend Taylor Burns ... when she decided to play the role of male breast inspector.

Meanwhile, over in Hawaii ... Eddie Murphy's girlfriend Paige Butcher rocked another tiny bikini.

Happy summer everyone.

Charlie Sheen is FURIOUS at Farrah Abraham for allegedly leaking their private text message conversation -- and TMZ has learned, he's already sent her the most epic rejection letter of all time ... calling her "a desperate guzzler of stagnant douche agua."

And that's just the beginning. Seriously. Charlie does NOT hold back. Here's the full transcript:

TMZ broke the story ... Farrah reached out to Charlie back in May via text message, saying she hopes to meet Sheen if she can score herself a role on "Anger Management." Charlie responded favorably, agreeing to meet up, but now ... it appears that's changed.

Translation: Farrah can forget about a playdate with Charlie ... but at least she's still a millionaire.

Charlie Sheen could be the next in line to have Farrah Abraham's back door hit him on the front side -- at least judging by the flirty way these two are texting each other.

Farrah Abraham has back-door'd her way into the 7-figure range ... 'cause the former MTV star tells TMZ she's a bona fide millionaire.

The 22-year-old just called in to "TMZ Live" to discuss her crush on Charlie Sheen ... when we asked her straight up if her foray into the world of adult entertainment has turned her into a millionaire.

But Farrah's swollen bank account isn't just from the sex tape -- we broke the story, she scored in the high 6-figures when she sold her sex tape to Vivid Entertainment. But she's also locking down endorsement deals ... and collecting checks for public appearances.

Farrah Abraham is involved in a full on textual relationship with Charlie Sheen, TMZ has learned -- and the two are now planning to hook up in person.

TMZ has obtained text messages that show the "Backdoor Teen Mom" porn star first reached out to Sheen back in May saying she hopes to meet Sheen if she can score herself a role on "Anger Management."

Farrah even took the initiative ... and asked Sheen out on a date -- either a parent playdate with their kids ... or an adult get together for some coffee.

Sheen's response: "Coffee is for amateurs and grandma."

He also said he's down to meet up ... because ... well, he's probably a big fan of her work.

Farrah followed up with Sheen and asked him to an event she would be attending with some "porn star ppl" ... but Sheen wasn't able to attend.

We're told they have stayed in touch ... and are trying to work out a date to see each other ASAP, but they're both busy with work ... and kids ... and porn.

Stay tuned ...
