Alex Pettyfer might be stepping closer to settling down with Elvis Presley's granddaughter, Riley Keough. According to Us Weekly, the leading man of "I Am Number Four" has asked the model/actress daughter of Lisa Marie Presley for her hand in marriage after only six months of dating.
The engagement rumor flew around after the "Magic Mike" co-stars enjoyed a lunch together at Le Petit Four in Los Angeles on Monday, March 12. Though the two, who were first caught kissing in October 2011, kept a low profile during the outing, paparazzi spotted that Keough was sporting an emerald ring on her left hand.
Before dating Keough, Pettyfer had a high-profile romance with "Glee" beauty Dianna Agron. The 21-year-old actor was once also linked romantically to his "Wild Child" co-star Emma Roberts. It was said that he has a tattoo that used to read "Emma" on his ring finger, but has covered it up since their break-up.
Keough, in the meantime, had Ryan Cabrera and Jonah Hill as her ex-boyfriends. The 22-year-old made her film debut alongside Kristen Stewart and Dakota Fanning as Marie Currie in "The Runaways".
