This picture has an interesting history, especially if you are a fan of Brad Pitt and Christina Applegate (how could you not be?!). This is a photo from the MTV movie awards in 1989 where Brad Pitt and Christina Applegate were on their first date. An award show is an odd place for a first date, but hey, Hollywood is a weird place. Despite being friends for a long time, this was their first official date, but it went south quickly. According to Hollywood history, she left Brad that very night for another guy.
As far as who the mystery guy is, no one knows for sure. It's been rumored to be Sebastian Bach, according to none other than Sebastian Bach, but Christina Applegate refuses to say. I'm not sure what woman in her right mind would reject Brad Pitt though!
