It's been a while since Robert Pattinson called it quits with Kristen Stewart so it only makes sense that he jumped back in the dating pool…with Riley Keough (a.k.a. Elvis Presley's granddaughter). According to X-17, the two were seen driving around his neighborhood and then he took her back to his place. To make matters even more interesting, Riley starred in The Runaways with K. Stew in 2010. It looks like R. Pattz is getting his fair share of summer lovin'.
