Aw, cheer up Justin Timberlake! It's not like you're going to have to sport this poofy dye job for too much longer!

We snapped the singer/actor on the set of The Social Network (aka The Facebook Movie), and while the clothes weren't so bad, it looks like JT wanted to cover up his horrendous hair as soon as shooting wrapped!

Then again, this is kinda reminiscent of his 'N Sync do from the 90s...hotness!
