Elvis's Eldest Granddaughter Finds Love

Talk about a hunka burnin' love! According to Us Weekly, the eldest granddaughter of Elvis Presley, Riley Keough, is engaged to her boyfriend of just six months, actor Alex Pettyfer. To add credence to the report, she's also been photographed this week sporting a nice hunka bling on her left ring finger. The rock doesn't appear to be a diamond, but it's certainly large and shiny.

Keough, 22, is the daughter of the King's only child Lisa Marie Presley and her first husband Danny Keough. Keough's famous bloodline--as well as her brooding good looks, which many have compared to her grandfather's--led her to the spotlight at an early age, as she made her modeling debut at just 14. She appeared on the catwalk for high-fashion houses such as Dolce & Gabbana and Christian Dior before progressing to the acting world several years later, first appearing opposite Kristen Stewart and Dakota Fanning in 2010's The Runaways.
Keough met Pettyfer, 21, while both were working on the upcoming Stephen Soderbergh film Magic Mike. Pettyfer, a British heartthrob who most recently starred in the 2011 thriller In Time, has previously been romantically linked to costars Emma Roberts (whose initials he has tattooed on his wrist) and Dianna Agron.

Keough herself has had a couple of previous high-profile romances--most notably with pop musician Ryan Cabrera and act.
