Sure, Kristen Stewart cheats on Robert Pattinson in a major way and now the guy is attached to all of the hottest women in Hollywood. First it was Rihanna, but now, he’s set his sights on RiRi’s BFF Katy Perry!

The new twosome met up for nice romantic dinner, and Pattinson’s sights moved a little, uh, south of Perry’s face! “She wore a tight, sparkly top and Rob was looking at her breasts all night,” said a source to The Sun (quotes via SugarScape). “He tried to avoid it when talking to her but as soon as she looked away to talk to someone else, Rob would sneak a peek.”

While the average girl may have felt a bit self conscious about the whole thing, Perry played along and actually enjoyed it!  “She was sat across from Rob but later moved next to him,” continued the source. “She was laying on the charm and playing the minx — tossing her head back, laughing at his jokes, touching his arm and twirling her hair.”

The singer has been a bit of a rock lately for the actor since the scandal, and has acted as a support system ever since. “Katy has been a rock for Rob. She has reassured him she is very much there for him just as he was for her when she split from Russell,” said a source to The Daily Star (quotes from Female First). She has urged him to take a break with her [Stewart].”

First, it was Robert Pattinson and Rihanna; and she was reportedly sexting him! “She got Rob’s phone number from a mutual friend and has been sending him sexy, funny texts to cheer him up,” continued the source. “At first, Rob thought someone Punk’d him. Eventually Rihanna convinced him she was for real, but Rob has been resisting her.”
