Alex Pettyfer and Riley Keough have reportedly gotten engaged.

The 22-year-old actress, and granddaughter of Elvis Presley, was seen wearing an engagement style ring on her finger yesterday adding to speculation she is set to tie the knot.

Us Weekly claims that the news was confirmed to them by a source and that the pair are committed to each other.

The young Hollywood stars have been dating for six months and are apparently ready to take their relationship to the next level.

Alex and Riley star together in upcoming movie Magic Mike where the 21-year-old British actor disrobes for the stripper movie alongside Channing Tatum, Matthew Bomer and Joe Manganiello.

The couple were first seen kissing in public back in October last year and have been inseparable ever since getting together a month before that.

The loved up twosome were pictured going for lunch at Le Petit Four in Los Angeles yesterday where Riley flashed her sparkler.

Alex has had romances in the past with actresses Emma Roberts and Dianna Agron while Riley has reportedly dated Ryan Cabrera and Jonah Hill.
