Lea Michele, 25, and Cory Monteith, 30, share both an on and off set romance. The two Glee! cast mates (and love interests) finally went public with their relationship in February of 2012. After claiming they were "just friends" for the majority of the show, the duo's final episode aired on May 22, 2012. I guess we will have to wait and see if their relationship flourishes or flops upon the shows end.
