Amanda Seyfried, another of Justin Timberlake's leading ladies, isn't afraid to kiss and tell either. Amanda and Justin worked together on the action film In Time. She told US magazine: "Justin was great - he had come from doing Friends With Benefits, where he basically had sex every day at work and so it was easy for both of us. We just kind of got it on, and then we were like, 'That was good!'"

We like her openness and honesty so we'll give them a healthy 4/5 when it comes to their kiss rating.
