The actor shared the happy news on Wednesday's Late Night with Jimmy Fallon and revealed that he thought Lopez was a lesbian when he first saw her at the Little Palm Island Resort near Miami in 2009."I was sitting in my usual spot, eating my oatmeal," Slater told host Jimmy Fallon

, "and this spot was famous for people proposing to each other. It was very, very nice. So she's there, and the next thing I know, she gets down on one knee and proposes to this older lady."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," Slater continued. "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, chasing gators and doing all that stuff."
