Justin Timberlake and his In Time co-star Amanda Seyfried may both look presidential, but Ms. Seyfried has sex on the brain.

In the October issue of W Magazine, Amanda opens up about filming sex scenes with Hollywood's leading young men. The starlet, who looks insanely proper next to JT as they pose in front of the American flag, says:

    "Sex scenes are great. A lot of my co-stars have been sexy guys my age, and so, why not? I’m not going to pretend it’s not fun."

As for how she'd rate Timberlake, Seyfried adds:

    "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.”

JT is one lucky man!
