'Guess the Butt' Round 1

A new game here at Idol Thought for all you cute boys lovers. It's called "Guess the Butt," and it's just like it sounds -- I'll post a picture of a famous lad's ass, and you all can leave comments guessing who it belongs to. I'll post a new butt every couple of days, so check in at Cute Boys of Pop Culture to see the latest.

Here's number one...

I'll give a hint tomorrow afternoon, and reveal his identity on Friday afternoon.

Happy guessing!
