Unlike most "My Favorite Scene" participants, McDonald took less than a second to name her favorite cinematic moment.
"Oh, I've got it," she said. "The movie Unfaithful, when [Diane Lane is] about to break up with [Olivier Martinez] and he does her in the hallway with her jeans around her ankles. I love infidelity as a genre of a film. I'm married and I've never cheated, so I like to watch it in movies."
NSFW, obviously.
