After meeting on the set of Glee in 2009, the costars began dating in early 2012
The couple took their relationship south of border for a romantic vacation in Cabo San Lucas in April 2012. "Cory is definitely having a positive effect on Lea. She's much less miserable these days," a source told Us Weekly in March. "Even when she was with Theo, she was always depressed being so far away from him and not getting to see him. She likes having someone with her that's actually there. Long distance is not her thing."
