The Glee star says she can't remember what her life was like before she started dating co-star (and love interest on the show) Monteith, speaking highly of him and revealing her love and trust for her beau.
"I don't even remember a time when he wasn't my boyfriend. No one knows me better than Cory," she says. "No one knows what it's been like to go through this more than he does. Feeling like you have that net underneath you allows you to jump higher and go farther. He makes me feel like I can do anything. For the first time in my life, I feel really, really settled and happy. I feel like the luckiest girl in the world."
Lea also jokes about her tendency to wear very revealing outfits to red carpet events and show off lots of cleavage.
"These babies are great [she jokes, pointing to her breasts]! They are my prizewinners. For a while they were out and about, showing off on Broadway every night, then they came to L.A. and were like, 'No one else looks like me here!' They were nervous to make their appearance but feel they've earned their place. So they asked if they could come out, and I was like, 'All right, you guys,'" she says.
"They definitely rose to the occasion, so I'm going to continue to give them more opportunities," she adds.
