Actress Annalynne McCord and former Prison Break star Dominic Purcell have ended their 15-month romance.

The 90210 beauty, who previously dated Twilight hunk Kellan Lutz, met Purcell on the set of the film Officer Down last year, and she previously opened up about how the pair "connected" over a conversation about moving out of Los Angeles.

McCord, 25, also brushed off their 17-year age difference, insisting she fell in love with the 42-year-old actor's intelligence.

However, the couple has since called it quits, according to UsMagazine.com.
