Pfft. No thought needed there. Ian Somerhalder ftw. That body and those icy blue eyes are are clear winner for me. Although, Tom was quite sexy as Lestat, so he gets point for that one.
Ian is sexy as Damon but...Tom killed it in that movie, this comes from a person that never thought that Tom would ever be anything other than just cute, until I saw that fantastic movie. So yes Ian's sexy with his abs and funny dance moves but Tom can be sexy without दिखा रहा है off his abs या any dancing moves या even being a funny guy and he proved it in the movie.
