Alpha Dog

Justin Timberlake: Talk about bringing the sexy back! Timberlake had a huge year, with multiple singles and that kick-ass HBO concert special, which only underscored what an amazing dancer JT is. He busts move after move, and does it while singing. He also works out with trainers,... more especially before a concert tour, or before a big movie role, as he did for "Alpha Dog." Woof.
