Hook Ups

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 ...

Somebody's got some explaining to do ... because model Kate Upton and "Dancing with the Stars" pro Maksim Chmerkovskiy ... the most random two people ever ... left a restaurant together Monday night in NYC.

There were reports the two were spotted canoodling inside ... but sources close to both camps tell us, they're not together. Not even close. They're just friends.

Justin Bieber might be getting handfuls of Miley Cyrus' Montantas -- which would totally ruin the sex appeal points she just earned with that insane twerking video ... almost.

Yep ... it's that good.

Miley Cyrus says it's "impossible" that she's more than friends with Justin Bieber ... despite the public flirting ... 'cause she's currently engaged to someone else.

Miley called in to Hot 99.5 in D.C. this morning ... and actually responded when the DJ asked if the photos on TMZ showing Miley and Bieber flirting in public this weekend prove they're "more than friends."

Her response: "I'm ENGAGED!" she said, chuckling. "I'm engaged. That is impossible."

It's an interesting statement for two reasons -- first, it clears up the rumors that she broke things off with Liam Hemsworth.

Second, when it came to being more than friends with Justin ... her answer isn't exactly a strong "no."

Miley was also asked about Amanda Bynes -- and she says some interesting stuff.

Give it a listen.

We're told Miley arrived first (she's a regular at the place) ... with Justin showing up around 1:50 AM and heading straight for Miley's table.

We're told the two hung out for roughly 15 minutes ... laughing and flirting together ... and they both left the theater at the same time, just after 2 AM. It's unclear where they went after the show.

Hours before the late-night rendezvous, Bieber's leopard-spotted Audi was seen leaving Miley's L.A. home on Saturday.

FYI -- Miley and Bieber have been friends for years ... but it seems like there might be something more going on between the two.

Prince Jackson clearly knows how to compartmentalize his life ... because he hit the town Tuesday night in low fashion, attending the premiere of True Blood, Season 6.

The 16-year-old and his GF, Remi Alfalah, were flanked by 3 bodyguards as they left the ArcLight in Hollywood.

People inside the screening tell us ... they were "touchy-feely" and seemed happy. Almost everyone was dressed up -- except Prince, which either makes him a slouch or a baller.
