Cameron Diaz flirted with Robert Pattinson at a Los Angeles event on October 27, even though the actor had reconciled with his Twilight co-star Kristen Stewart a month earlier, reports Us.

The flirtatious encounter took place at a gala at the L.A. County Museum of Art. According to an onlooker, the 40-year-old Diaz "was pretty obvious." The source claims, “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."

Pattinson and Stewart were spotted just two days earlier at a Prince concert at Hollywood Sayer's Club, where a spy observed them “kissing passionately.” According to the witness, "It was like watching one of their movies!"

Pattinson and Stewart split for a time after she revealed an affair with her Snow White and the Huntsman director Rupert Sanders.

I'm not sure there are many women who WOULDN'T flirt when Robby was around you know?
