Pictures of Justin Timberlake Shirtless on the set of Now

1 / 38

Justin Timberlake turned 30 yesterday, but the kind actor was the one giving a gift — he stripped down and went shirtless to take a dip while shooting Now in LA! The sight of Justin's hard-earned abs was a welcome one for his many female admirers, and in honor of his milestone birthday we took a look back at 30 ladies who have been lucky enough to get close to the sexy star. Justin returned to work last night following a weekend of fun at the Screen Actors Guild Awards, where he joined the hot guys on the red carpet and supported his film The Social Network.
