In Rihanna's video for Rehab, the guy looks like Justin Timberlake. Is it?

Rihanna has a video out for her song rehab. It has been bugging me because it looks like justin Timberlake in some parts, but in other parts it doesn't. He's the one who's on the motorcycle and under the shower and ends up being close to kissing her. So is it him?
