Christian Slater made a big announcement on Late Night with Jimmy Fallon on Feb. 27: He is engaged to girlfriend Brittany Lopez! Christian and Brittany have been dating for more than three years and even admits that he thought she was a lesbian when they first met. "This girl came walking along with another lady, a slightly older lady. I was sitting in my usual spot, eating my oatmeal...and this spot was famous for people proposing to each other. And the next thing I know, she gets down on one knee and proposes to this older lady," reveals the actor. "I thought I had just witnessed a nice lesbian engagement, so I was coming over to say congratulations, but it turns out it was her aunt, and she was just trying to help her aunt capture the beauty and the romance of the moment. She was making a joke, and I witnessed it, and it intrigued me, and the next thing I knew, we were hanging out in the Everglades." Christian was previously wed to Ryan Haddon. They share two kids, Jaden, 13, and Eliana, 11.
