In an interesting twist of events, it turns out it wasn’t Riley Keough in the car with Robert Pattinson this past weekend. Her rep has confirmed that she is not dating Kristen Stewart’s ex.

The granddaughter of Elvis Presley, and daughter of Lisa Marie Presley, is “isn’t dating Rob,” her rep told Just Jared. “And I can confirm that Riley was not photographed at all this weekend.”

As we previously reported, Pattinson, 27, who split from longtime friend Kristen Stewart in May, was seen driving around with a girl in the car around his Los Feliz, Calif. home this past weekend and it was speculated that it was Keough.

A source even said, “They're inseparable. Rob loves the fact that Riley is Elvis's granddaughter - that's true Rock'n'Roll royalty in his eyes.” Keough worked with Stewart in 2010 on the film The Runaways.

She has been linked to actor Alex Pettyfer, but they split earlier this year.
