McDreamy & McSteamy Join Valentine's Day Cast

Grey's Anatomy costars Patrick Dempsey ("Dr. Derek Shepherd") and Eric Dane ("Dr. Mark Sloan") have signed on to star in the Garry Marshall movie Valentine's Day. As previously reported on Pop Wenches, the romantic comedy's ensemble cast includes Julia Roberts, Anne Hathaway, Jennifer Garner and Bradley Cooper, among others.

Dempsey will play a doctor who is dating Garner's character, but fails to mention that he's married (is Garner's character going to be named "Meredith Grey, Season 1"??). Dane's character is a successful, but aging quarterback who is pondering retirement.

Valentine's Day is slated for a February 12, 2010 release. [Entertainment Weekly]
