While the tabloids are still playing fun guessing games as to the how, where, when, and if of Robert Pattinson and Kristen Stewart’s hooking up/relationship/affair/whatever, OK! is taking a bold stance. They claim that not only are Robert and Kristen together, for real, but that Pattz is now totally cheating on Kristen with his pretty Remember Me costar Emilie de Ravin. This is actually not quite a bold stance – Star Magazine was claiming the same thing when Emilie and Pattz had barely even met. But OK! has the photo evidence! Many paparazzi got this “photo evidence” of Emilie and Pattz making out on a beach last week – unfortunately, it was for the film. Still, OK! claims that when Kristen saw the pics, she “flipped out.”

It wasn’t just the heart of every Robert Pattinson fan that sunk when they saw photos last week of him smooching co-star Emilie de Ravin while shooting scenes for their upcoming film Remember Me. His on and offscreen love interest Kristen Stewart was none-too-pleased with what she saw.

A source close to the couple says, “She knows screen kisses are part of Rob’s job, but it doesn’t make things easier, seeing sexy photos of him and Emilie in full lip-lock.” A friend of Rob’s puts it more explicitly: “Kristen saw a photo of them kissing and flipped out.”

And according to some who were on the beach for the scene that day tell OK! that both R-Pattz and Emilie seemed to be enjoying the scene. “Everyone else was setting up for the next shot, but Rob and Emilie stayed where they were,” says the eyewitness. “Emilie snuggled with him for at least 10 minutes. She was sitting with part of her body pressed up under his arm and they were making each other laugh. They’re definitely getting close — you can tell it’s more than a work relationship.”

The co-stars have also been spending some time together when they’re not filming. On June 19, they hit the posh Soho House, where they shared plenty of face time in a private smoking room. Just three days earlier, the duo were spotted at Gemma, a restaurant at The Bowery Hotel, one of their favorite haunts.

“They spent a lot of time telling jokes, laughing and whispering in each other’s ears,” an eyewitness tells OK!. “At one point Emilie took Robert’s Ray-Bans and was playfully wearing them before putting them back in his shirt pocket — it was very flirty. Rob was so sweet and attentive; if I didn’t know anything about him, I would think Emilie was his girlfriend!”

Whether or not she believes anything’s going on between her man and his beautiful blonde co-star, friends tell OK! that the incident has “made Kristen nervous and more determined to visit him in New York… It’s clear Rob and Emilie have a lot of movie chemistry. Kristen is hoping it hasn’t spilled over into real life.”

Emilie was snuggling with Pattz? They’ve been hanging out off the set? Flirty drinks late at night? Emilie, you slut. Get her, Twihards. I actually don’t care for Emilie – she was on Lost for the first two seasons, and while I felt for character, Emilie isn’t really the best actress. And she apparently has that nasty habit of seducing whatever man is around. Which makes for good gossip, but not when lives are at stake by roving packs of rabid Twihards.

So, is Kristen really jealous? Does she have anything to be jealous about? I mean that both ways – are Kristen and Pattz in a relationship, and if they are, is Emilie some kind of threat? Judging Kristen solely from how she seems to me, I’d say that she knew that Pattz would flit off to whichever attractive girl was around, and Kristen wasn’t expecting Pattz to stay devoted to her. Just my take – she’s a smart enough girl to know a player when she sees one.
