Justin Timberlake has all the reasons in the world to be confident: His acting career continues to blossom and there’s a growing cry for him to return to his musical roots. Still, one gossip magazine is claiming that Timberlake’s been feeling a little antsy and insecure lately. Indeed, according to In Touch Weekly Timberlake is “horrified” over his thinning hair.

In Touch quotes a source saying that Timberlake fears that his hair will ruin his dating life. The source says, “He’s keeping his hair super-short so no one notices.” Timberlake’s curly mane was a huge draw for him during his heartthrob days in the boy band *NSYNC.

The source added, "He's using specially formulated shampoo to promote hair growth.  He certainly doesn't want to go bald!"

Timberlake, who famously dated Britney Spears, recently broke up with actress Jessica Biel. He's since been linked with Black Swan co-star, Mila Kunis.
