Robert Pattinson's New Galpal: Elvis' Granddaughter? He's spotted with Riley Keough By Evann Gastaldo, Newser Staff Posted Jul 3, 2013 10:23 AM CDT Updated Jul 3, 2013 10:50 AM CDT 12 comments Comments Elvis Presley's granddaughter Riley Keough attends the Anna Sui 2008 Fall Collection during Fashion Week, Wednesday, Feb. 6, 2008, in New York. (AP Photo/Peter Kramer) (Newser) – Well, this is awkward: Robert Pattinson was spotted driving to his house with a "mystery girl" Sunday, and she's now been IDed as model/actress Riley Keough. That's notable for three reasons: Keough is the granddaughter of Elvis Presley. She co-starred with Pattinson ex Kristen Stewart in The Runaways. (Pattinson and Stewart most recently split in May.) She's close friends with Stewart, according to the New York Daily News. In fact, she attended Stewart's April birthday party, as did Pattinson. So, are Keough and Pattinson dating? Most outlets seem to be spinning it that way (a source tells the ever-trustworthy Daily Mail the two are "inseparable," while another tells Hollywood Life that Rob "is so happy that he can trust someone again"). But X17 notes that maybe she was actually running interference for Kristen, trying to reunite the Twilight lovers.
