Penn Badgley’s Unkempt Mane: When Bad Hair Happens to Hot Dudes (PHOTOS)

Amanda Hasaka / July 28, 2011

We love us some Penn Badgley, but what is going on with his hair?!

The dreamy Gossip Girl actor was spotted on set of in NYC on Thursday afternoon and it looks like the big apple’s humidity got the best of him (or his hair, at least). While he usually slicks his hair back for his role as Dan Humphries on the hit CW show, the 24-year-old actor let his natural curls flow freely. (We do give him bonus points for the Jimmy Fallon shirt, though).

He wouldn’t be the first!

Remember when Pete Wentz grew out his little fro? Yeah, we can’t forget about it either!

The fact is, there have been plenty of other Hollywood fellas who haven’t had the best judgement when it comes to hair upkeep, so check them out in the gallery!

Don’t think we forgot about the ladies! Take a look at some lady offenders below.
