Kristen Stewart’s jealousy over Megan Fox driving Robert Pattinson nuts

As you have no doubt heard, Robert Pattinson and Kristen Stewart have quite a thing going on…and off…then on again…for a while. Well, now here’s the latest on that state of events:

It seems young Rob’s been complaining to pals that Kristen’s romantic flip-flops are driving him nuts. But Rob’s biggest gripe was Kristen’s reaction to his getting friendly with co-host Megan Fox. The two were on stage at the ‘Teen Choice Awards,’ and once his segment was over Kristen cornered him backstage and really got steamed;

“Rob couldn’t believe it,” says a friend of the actor. “Kristen plays hard-to-get with him, then gets jealous over Megan. And she really ripped him, saying stuff like, ‘I saw you put your arm around her…you touched her.’ Rob thought it was ridiculous and just walked away.”

But Kristen, apparently, was not even done. The friend told the Enquirer she’s been on Rob’s case over this ever since, “Rob’s getting tired of the constant drama. Kristen keeps going back to her boyfriend, then comes back to Rob – over and over?!” Rob’s pal told the scribes. “She pushes him away, then has the nerve to complain about other women. It’s ludicrous. The girl needs to grow up!”

Yes, and apparently so do some people at Summit. ‘Twilight: New Moon’ debuts in November, and mind-candy like this does not help their case…
