Robert Pattinson Hits a Concert in LA — but Who Is His Lady Friend?

Robert Pattinson and Dylan Penn attended a concert.

Robert Pattinson checked out an Arctic Monkeys concert at LA's Wiltern Theater this week with a group of female friends, including one tall blonde. Robert has recently been linked to Sean Penn's 22-year-old daughter, Dylan Penn, and the couple has reportedly been dating for "a month or two." While Robert has been rumored to have hooked up with a number of ladies, like Riley Keough, Katy Perry, and trainer Sydney Liebes, since his split from Kristen Stewart earlier this year, sources claim that he and Dylan may be the real deal.
