Hook Ups

Arnold Schwarzenegger's no longer just wining and dining new GF Heather Milligan ... he's showing her off to friends during double-dates.

Arnie and Heather hit Spago in Bev Hills this week with another couple ... we're told the the guy is an old friend of Arnold's.

By the way, Heather is reportedly 38 years old ... while Arnie is 65 -- and his buddy seems to be around that same age.

Sooo ... gotta wonder what the dinner conversation was like during the foursome's night on the town.

Justin Bieber let his fans know he's back with Selena Gomez -- but only for a few moments -- as he posted a pic of himself getting cozy with SG ... and then quickly deleted it.

Gomez sparked reunion rumors when she jetted off to Norway to meet up with JB, who is touring there.

As we previously reported ... Selena and Justin have seen each other periodically since breaking up at the end of 2012. We're told he's been "tortured" because she's been giving him mixed signals.

Posting a pic for the world to see and then deleting could qualify as a "mixed signal."

Britney Spears isn't the only one back in the dating pool -- former fiancé Jason Trawick was spotted out yesterday with a slick new 'do and a tatted up new woman ... who looks like she could be Rachel Uchitel's rebellious younger sister.

"American Pie" star Eddie Kaye Thomas sure knows how to pick 'em ... the woman who allegedly barricaded herself inside his home with a knife after a one-night stand has a history of SERIOUSLY wearing out her welcome.

TMZ has learned ... 31-year-old Roxanna Bear was arrested twice in February ... once for public intoxication and once for trespassing.

Police say Roxanna was loitering around the Regent Beverly Wilshire hotel -- where she was NOT a guest -- on Feb. 24. She refused to leave when hotel security confronted her ... so they called the cops.

The other arrest came just a few days before, when police say Roxanna was stumbling drunk in the middle of Wilshire Blvd. She was allegedly combative during both arrests -- though no knives were involved.

Also, we've learned the L.A. County DA just hit Roxie with 5 charges for the incident at Eddie's house ... including vandalism, exhibiting a deadly weapon and resisting arrest.

As TMZ first reported, EKT picked her up the night before at Mel's Diner ... cops had to use tear gas to get her out.

Justin Bieber is not over Selena Gomez ... in fact, she's still very much in the palm of his hand.

We started looking closely at pics of Justin ... and we came across this one (left) of Justin leaving a museum in Amsterdam, and his sorta ex-GF was along for the ride ... as the screensaver on his iPhone.

Justin's background image of choice is clearly a pic of Selena. The sultry pic is from a March 4 photo shoot, TMZ has learned.

Only question is ... did she send it to him, or was he keeping tabs on her?

As TMZ reported yesterday, she flew into Oslo, Norway, to hook up with her on-again, off-again BF.

Now it's clear ... their continuing obsession is DEFINITELY mutual.

Brooke Shields is here to save your sex life by revealing which piece of furniture is best for getting busy -- love seats or recliners? Dim the lights ... your living room's about to get way sexier.

Selena Gomez has landed in Norway ... and sources tell us she's on a mission ... to hook up with Justin Bieber.

Selena was spotted getting off a plane at the airport in Oslo ... just about the time JB was getting ready to hit the stage.

Beliebers -- who obviously know where Justin is at all times -- have been buzzing about a possible rendezvous ever since a Norwegian pop star tweeted about seeing Selena on the flight from L.A. to Oslo.

Sources connected with JB tell TMZ ... it's no coincidence they're in the same country at the same time.

As we previously reported ... Selena and Justin have seen each other periodically since breaking up at the end of 2012. We're told he's been "tortured" because she's been giving him mixed signals.

So much for never ever ever getting back together. Selena, Taylor ... same thing.

Y'know what they say about stranger danger -- the chick who pulled a knife on Eddie Kaye Thomas had just met the "American Pie" star less than 24 hours earlier ... TMZ has learned.

As we first reported ... SWAT responded to Thomas' house Wednesday evening after Thomas called 911 ... and remained in a standoff with the woman for a couple hours ... before forcing her out with tear gas.

She was taken into custody, checked out at a hospital, and then booked for felony vandalism.

But here's the best part -- according to law enforcement sources Eddie met the chick the night before at Mel's Diner, and brought her back to his place.

Typical one night stand, we're guessing ... until Wednesday afternoon when Eddie says they got into an argument, and she pulled the knife.

During the standoff, we're told the woman smashed up a phone, a guitar ... and generally trashed Eddie's house before cops smoked her out.

"Buckwild" star Shae Bradley -- whose latest role is in a hillbilly sex tape -- thinks it's her creep ex-bf Jesse J who's been pimping their homemade porn ... and she wants no part of it.

Shae tells TMZ ... "The materials are being used against me and it should be illegal. I am ashamed of my mistake and deeply regret it."

She may want to reconsider ... TMZ has learned YouPorn.com is willing to pay Shae $50,000 in cash if she'll sign off. To sweeten the deal they'll throw in a year's supply of cigarettes ... any kind her hillbilly heart desires. But Shae tells us ... "No way."

TMZ broke the story ... the on-again-off-again couple videotaped themselves having sex a year before they became reality stars.

But sounds like Shae wants more than smokes and dead presidents to let the vid go public.

A couple of "Buckwild" Stars are horning in on Farrah Abraham's sex tape territory ... TMZ has learned.

The stars are on-again-off-again couple Shae Bradley and Jesse J -- and they engage in what we're told is "trailer park sex." Translation -- nothing fancy, down and dirty and a tad tacky -- she doesn't even take her shirt off.

We're told "Buckwild" producers knew about the tape before they started shooting the show, and told Shae and Jesse to keep their mouths shut. But now that the show has gotten the ax, it's being shopped around.

Unlike our fair Farrah, it's unclear if Shae and Jesse are behind the possible sale of the XXX vid.

Shae tells TMZ, "Yes there is a sex tape and I regret making it with someone who I obviously couldn't trust and is looking to exploit the relationship we had."

Might as well tailor that green jacket for Tiger Woods ... 'cause his 5'10" blonde good luck piece -- aka Lindsey Vonn -- showed up for round one of The Masters.

LV turned up at Augusta National to support her man wearing a giant floppy hat ... perhaps to make sure cameras can find her all day while she follows Tiger?

We're betting Tiger doesn't care what she wears 'cause he's been on a tear since going public about banging Lindsey -- winning two tournaments in a row, and 3 out of his last 5.

BUSTED!!! Justin Bieber's freeloading friend is NOT hooking up with Selena Gomez, even though he went to Herculean lengths to make it seem that way ... and we have video proof.

King Kevi -- who became famous-adjacent recently by living in Justin's house and throwing ragers with lots of girls, bongs and beer -- caused a stir when these pics (below) surfaced, showing the fake royalty appearing to leave Selena's San Fernando Valley estate Saturday night.

Various media reported Kevi -- the up-and-coming nobody -- was inside her house and "hung out." But we got our hands on surveillance footage taken the night in question ... showing Kevi posing in front of Selena's house while camera flashes went off ... but never making it past the gate.

Selena wasn't even home at the time the photos were taken.

In other words ... it was all a setup by the guy who is mooching off the Biebs.

He's no Kato Kaelin.

2:45 PM PT -- King Kevi tells TMZ the whole thing is a simple misunderstanding -- saying, "I was there to drop off something to a friend at the party. I walked multiple times to the front gate to try to call my friend and every time I had to chase off the photog."

He adds, "After the last attempt, I went to my car to leave and that's when my friend called me to come inside. When I backed in, I gave him another call to open the gate and he didn't pick up so I left because I saw the photog come back around."

Sad news from the Diddy camp ... the rap mogul says he's 100%, positively NOT having sexual relations with model Kate Upton ... despite the fact it would be totally awesome if true.

Reports surfaced this morning that Diddy and Double-Diddy were spotted making out at a NY restaurant last week ... and the Internet instantly exploded with jealousy.

But Diddy says it just ain't true ... tweeting, "Attn all Media. I don't even know Kate Upton personally! I'm not dating her! What's being reported is not true. END of story!"

Sad ...

A rep for Kate also tells TMZ ... Kate and Diddy "barely know each other" and they are definitely not dating.

Farrah Abraham is finally copping to shooting a full-on porn -- with A-list porn star James Deen -- but says even though it was intended for her personal scrapbook ... she's willing to sell it for $2 million.

The ex-"Teen Mom" star's reason for shooting the XXX video is simply the best ... telling TMZ she wanted to immortalize her smokin' hot 21-year-old body -- for her personal collection -- so she could look back on it when she's old.

Guess Olan Mills was booked?

Farrah, who initially denied a sex tape existed, says she's pissed at her penis-for-hire -- because Deen let the cat out of the bag ... telling our camera guy the whole staged shoot was Farrah's idea.

Farrah says she wants nothing to do with Deen now (we suspect that's mutual) and took a parting shot, telling us -- "If my ex-boyfriend Derek were alive, I would've rather it had been him with me."

Farrah's baby daddy Derek Underwood died in a car accident in 2008.

As for the sex vid going public ... Farrah says her lawyer is dealing with a porn company, and she "will not be settling for anything less than a couple million" bucks.

Here's a shocker ... "Teen Mom" Farrah Abraham's so-called "sex tape" with porn star James Deen was a SETUP ... devised by Farrah herself ... so says her XXX co-star James Deen.

Deen tells TMZ, he was approached by an unidentified porn company to shoot the porno with Farrah over the weekend ... and they did. He says the plan was to pass the porn off as a "sex tape," but the plan fell apart.

Deen believes the ruse began to unravel Sunday when he and Farrah were shot leaving the Vivid Entertainment offices, holding hands.

He says, "I think what happened is that [the porn company was] going to pass it off as a 'sex tape' and somebody saw us coming out of a building together and people asked me what's going on ... so I was like we're making a porno!" (Deen wouldn't say if the "company" was in fact Vivid.)

And the kicker ... despite Farrah's poorly-worded protests, Deen says she was the one behind it the whole time, telling us, "Everybody's trying to make it this story, but really [Farrah] wanted to make a sex tape."

But how good was she really? We had to ask ... and Deen doesn't hold back.

Vince Vaughn, Robert Pattinson and Joaquin Phoenix joined forces for what seemed like a totally random bros night out -- until our crack team uncovered their little blonde bond.
