AnnaLynne McCord and Dominic Purcell split after over a year

25-year-old "90210" star AnnaLynne McCord has ended her relationship with 42-year-old "Prison Break" actor Dominic Purcell after 15 months together, reports Us Weekly. The couple met on the set of their film "Officer Down," which has yet to be released.

Sources tell the mag that McCord decided to break things off after her two sisters got engaged, when she began to reevaluate her relationship. The same insider says Purcell was "more into AnnaLynne than she was into him."

"90210" returns on Monday, Oct. 8 at 8 p.m. EST on The CW. If you're curious about what else AnnaLynne has been up to, check her out in the clip from her wildly disturbing new film, "Excision," below.
