Elvis Presley's model/actress granddaughter Riley Keough has reportedly reunited with her former fiance Alex Pettyfer after they were spotted holding hands at a Los Angeles premiere on Monday (12Aug13).

Keough, the daughter of singer Lisa Marie Presley, met the British actor on the set of stripper movie Magic Mike in 2011 and the pair became engaged last year (12).

The couple reportedly called time on the relationship earlier this year (13), but the romance appeared to be back on again as the pair attended the screening of Lee Daniels' The Butler on Monday.

An eyewitness tells UsWeekly.com the stars were "holding hands", adding that Keough was wearing a ring on her left hand.

The report comes just weeks after Keough's representative denied reports suggesting the beauty was dating Twilight hunk Robert Pattinson.
