It's easy to see Justin Timberlake as the "perfect" boyfriend. After all, he's always been so committed to his GFs, and we thought he was a serial monogamist. After a little research, we realized Justin's not such an innocent player in the game of love.

Peek at his past GFs and weigh in on his perfect match!
