Some celeb couples can handle May-December romances, like Catherine Zeta-Jones and Michael Douglas. And some can’t, like Demi Moore and Ashton Kutcher. Sadly, we’re adding 90210 beauty Annalynne McCord and Prison Break star Dominic Purcell (and their 17-year age difference) to the latter list.

AnnaLynne, 25, and Dominic, 42, met while filming Officer Down in early 2011. (No, we haven’t heard of it either — that’s because it's in post-production limbo!)

A source tells Us that AnnaLynne ended the relationship after her sisters’ recent engagements caused her to reevaluate her relationship with Dominic, but another insider says that she “fell for Dom hard,” so take everything with a grain of salt.

AnnaLynne had previously dated Twilight’s Kellan Lutz (who appeared in six episodes of 90210). Dominic, meanwhile, was previously married to Rebecca Williamson, with whom he has four children.
