and Riley Keough have reportedly
made the leap from friendship to romance now that he is no longer dating his former 'Twilight' co-star Kristen Stewart.
Riley, 24, is the granddaughter of the late rock and roll icon Elvis, and the daughter of Lisa Marie Presley.
She first gained fame as a teen model before embarking on a film career at age 19, co-starring in 2010 with Dakota Fanning, Tatum O'Neal and Kristen Stewart in 'The Runaways.'
Since that time the 24-year-old model-actress has traveled in the same social circles as Rob's former love interest Kristen, and by association, with Rob Pattinson.
Keough attended Stewart's 23rd birthday bash in April at Mexican restaurant Cantina Malo in Silver Lake, California. Perhaps it was during that particular event that she and Pattinson discovered their mutual attraction?
They continued to rubbed elbows at Dior events in May and June -- he as the face of Dior Homme and she for Dior Cherie until very recently.
At any rate Riley and Rob have been seen out and about in Los Angeles and are reportedly planning to spend the 4th of July holiday together before he heads to Toronto next week to begin filming 'Map to the Stars.'
Off-again flame Kristen Stewart is in Europe for Paris Fashion Week activities.
