Celebrity Cameos in Videos: Scarlett Johansson in Justin Timberlake’s ‘What Goes Around… Comes Around’

Accompanying what could be Justin Timberlake's steamiest track to date, the nine-minute video to 'What Goes Around... Comes Around,' from his 'FutureSex/LoveSounds' album, gave starlet Scarlett Johansson her first step into the music industry playing the other half of a tumultuous, passionate relationship. Director Sam Bayer called ScarJo "the Marilyn Monroe of the 21st century." A stretch, perhaps, but with all of the yelling, kissing, caressing and car wrecks going on in this video, you gotta admit the girl does know how to hold it down.
