Robert Pattinson spotted with Sean Penn's daughter, Dylan Penn, and dating rumors swirl.
Robert Pattinson was spotted at a birthday party with a mystery woman.
Pattinson and Penn were also spotted partying at the Viper Room in West Hollywood to see a show, then went to the Chateau Marmont shortly after for food and drinks.
A source tells E! News that the two are no more then friends. They met through ex-girlfriend, Kristin Stewart.
However, a source told People "They've been dating for a month or two. He's crazy about her."
dating rumors also rose when Pattinson was seen with trainer Sydney Liebes at Harley Pasternak's Gym where she works, but he was only training with her when Harley was absent.
In May, Pattinson broke up with Stewart after her affair with director, Rupert Sanders, went public. The two tried to work it out but eventually called it quits after three years of dating.
Pattinson and Penn have not confirmed their relationship.
