Two weekends ago, there was an OMG SCANDAL in which Robert Pattinson was seen in the vicinity of a girl who was not Kristen Stewart. OMG. Actually, it was a bit more scandalous than that – Sparkles and Sarah Roemer were seen hanging out at a club and then they got into the same car. OK! Magazine even claims that Sparkles “stroked” Sarah’s hand in the car. OMG I bet she’s pregnant now!!! Anyway, OK! Mag has a hilarious/sad story about what’s really going on between Kristen Stewart and Robert Pattinson: basically, Kristen is a neurotic mess over Robert’s flirtations…? Who buys that? But I do buy that Rob “adores” Kristen:

It was the canoodle felt round the world: On Dec. 3, Twilight’s Robert Pattinson left L.A.’s La Poubelle restaurant with actress Sarah Roemer, then squeezed into the backseat of a waiting car and stroked her hand — this with Rob’s on-and-off- screen love, Kristen Stewart, 5,000 miles away in England, filming Snow White and the Huntsman. So speculation flew: Was Edward cheating on Bella? Twi-hards were aghast — and Kristen was furious.

“Rob’s one of the world’s biggest heartthrobs and Kristen’s never been able to relax the whole time she’s been with him,” an insider tells OK!. “This was, like, her worst fear realized.”

Rob, 25, denies any infidelity, claiming it was an innocent night out with platonic pals. But now the brooding screen vampire is terrified that Kristen, 21, might come home and toss his guitar and hoodies into the street — and he’s desperately trying to save their relationship.

“Rob’s in total panic mode at the thought of losing Kristen,” the insider says. “He’s desperate to keep her and is virtually groveling on bent knee.”

To return to Kristen’s good graces, Rob is buying her a spectacular Christmas present: A diamond ring.

“He’s designing it himself and wants to put an inscription inside,” a friend of Kristen tells OK!. “He asked if their initials were too cheesy, but Rob really is a hopeless romantic. He adores Kristen,” the friend adds. “He wakes up thinking of her and goes to bed thinking of her. And he would do anything for her.”

Another measure of Rob’s devotion? In a recent interview he hinted at having children with Kristen. Asked if he’d like to be a young father, Rob replied, “I think that would be nice.”

There appears to be some work to do first — the Sarah flap is only the latest bump of a rocky period in Robstenland.

“Kristen and Rob have been arguing a lot,” says a pal of Rob. “They’re overworked; their tempers are short.” But more than anything else, what’s fueling the discord is just plain jealousy. Working on separate film projects in between Twilight stints, Rob and Kristen have often been continents apart. Texting and Skyping only go so far both young stars face temptation. In the early days of the Twilight phenomenon, of course, it was mainly Rob who was fending off amorous advances from fans — and fueling gossip. While making 2010’s dark romance Remember Me, for instance, he got uncomfortably (for K-Stew, at least) close to co-star Emilie de Ravin.

“Rob loves the attention he’s been getting from hot women,” his friend tells OK!. “Growing up in London, he never had that. So he’s been taking advantage of his popularity by flirting.”

But, increasingly, it’s becoming a two-way street. Much like Twilight alter ego Bella Swan, Kristen has become more comfortable with her sexuality.

“Having so many enamored male fans drool over her has made Kristen feel the sexiest she’s ever felt,” says Rob’s friend. “Because of her newfound confidence, she finds herself wanting to flirt more. Kristen claims it’s all in good fun.”

Rob isn’t laughing — he’s especially steamed over Kristen’s recent outing with On the Road co-star Garrett Hedlund, and the attention she lavishes on easy-on-the-eyes Twilight co-star Taylor Lautner. In fact, Kristen’s friend suggests that Rob may have played up the Sarah incident just to make her jealous: “He does everything to keep Kristen’s attention. She doesn’t tend to be the type to dote on him, and it drives him crazy.”

Clearly, the next few weeks are crucial for the golden couple’s relationship. “Rob’s saying all the right things,” an insider says. “Kristen wants to trust him more than anything, and there’s no doubt she’d love to be Mrs. Pattinson one day.”

The holidays may provide a cooling off period. Kristen is spending Christmas in L.A. with her mother, Jules, while Rob flies back to London to be with his folks. Kristen’s friend is hopeful the romance will survive.

“They’re young, in love, rich, famous and their careers couldn’t be better,” the pal tells OK!. “For them it’s really just about enjoying their time together. Kristen is always saying they should live in the moment and not worry about what comes next.”

I tend to believe that Kristen is the one who will cheat, if I had to make a choice between the two of them. Kristen allegedly screwed around WITH Sparkles when she was with her previous boyfriend, Michael Angarano – and I do think there was some overlap between the two relationships. Kristen seems really good at playing the game of keeping Robert interested in her, and I suspect she’s a withholder, and he’s a bit of a masochist. He’s always reaching out, and she’s always pulling away. That’s what makes them work. For now. Give it another year.
