"He's cute. He plays my boyfriend in the movie, which is very convenient," she joked when she stopped by "The Tonight Show" to chat with Jay Leno on Thursday. "I met him two weeks before filming. We went on a Starbucks date. That's what you do when you meet your co-star that you have to be kissing for months and months and months, and I was sold."
That encounter made kissing him on the very first day of filming very easy. "[Our first kiss] was on the first day of filming in the movie," she said. "We have this scene where we frolic in the water. So I frolic very well apparently, and after that I got to keep him."
Cyrus and Hemsworth have only been dating for about 10 months, but she says that they've already checked out each other's parents to see how well they will age in the future. "He looked good and he's got a full head of hair," she said about her beau's dad. And as for her mom, Tish, Cyrus joked, "My mom's hot, so ... No, I'm very aware [she's hot]. I think that was the only reason why I had any guy friends."
