Kristen Stewart better watch out. She may have gotten her man back, but another hot actress is reportedly trying very hard to take her place.

Us Weekly reports that Cameron Diaz was “ferociously flirting” with Robert Pattinson at the LA County Museum of Art's Art + Film Gala on October 27. A witness says, “She was pretty obvious … Cam was seated next to Rob at dinner. She was touching his arm, doing her big Cameron laugh at everything he said and trying really hard. He was polite, but not having it."

According to another source, R.Pattz and K.Stew had just been spotted “kissing passionately” at a private Prince concert just two days before the LA gala.

But Us found not only one, but “three witnesses” who claim they saw Cameron trying her best to get R.Pattz’s attention. Something tells us she won’t get very far with the smitten hottie. He and K.Stew looked like they were totally in love while promoting Twilight: Breaking Dawn - Part 2 in a recent interview, and we’d love it if they stayed that way!
