Tara and Kehayov tied the knot Saturday on the Greek isle of Santorini. We're told the wedding took place on the roof of the luxury Mystique Resort, overlooking the ocean.

Sources close to Crystal tell TMZ, she officially moved into Jordan's Hollywood Hills home a couple weeks ago -- but she's been crashing at the place on and off for months ... while she split her time between L.A. and San Diego.

Surprisingly, we're told the two are NOT dating -- they're just really good friends ... and as we previously reported, they're both working hard to produce Crystal's new album.

Tom Cruise really put the squeeze on his wife Katie Holmes last weekend in L.A. -- copping a SNEAKY feel of her ass at a Katy Perry concert -- and TMZ has obtained the hands-on footage.

We told you yesterday ... Tiger Woods ex-wife is dating marketing exec Jamie Dingman, whose dad is a billionaire tycoon. But before Elin, sources tell TMZ Jamie and Rachel were an item -- and there was a little bit of an overlap with Jamie and Tiger, but Jamie bowed out to the golfer.

In fact, when Rachael got serious with Tiger, Jamie joked with her, "That ok. I'll date his wife, Elin."

And get this ... at the time the Tiger Woods scandal broke, Jamie was living with Rachel in a MIami home.

And there's more. Remember the name, Jen Madden? She's the one who sold the Tiger Woods story in the first place, and she got the info because she stayed at the Miami home and overheard Rachel tell Jamie about her affair with Tiger.

The guy is Jamie Dingman, a New York marketing exec.

A Swedish photo agency came to TMZ with what they said was a photo of the two, kissing and hugging outside Elin's apartment in Sweden. TMZ has seen the photo -- but the agency decided it wanted to hold it ... at least for now.

Jamie's dad, Michael Dingman, is a very wealthy investor. Jamie specialized in Russian private equity funds and he also owned an Indy car-racing team.

He reportedly dated Bridget Moynahan, Tom Brady's baby mama. He was also linked to Princess Madeleine of Sweden, but the New York Post says they were just friends. It does, however, provide a Swedish connection.

The photos have appeared on a Swedish website Expressen.tv as part of a video package. Good luck translating.
