That boy is Jamie Bamber

Jamie Bamber is a british actor last seen on TV series Battlestar Galactica. To be honest before the series I would hardly turn my head and check him out, but short hair and dirty pilot outfit sure changes a person a lot!

Check out these shirtless stills from the series; 1, 2, 3, 4 and 5. He has done a very nice interview with OUT magazine, in which he comments on queer possibilities of Battlestar Galactica.
