49. Alexander Skarsgard
True Blood hottie Alexander Skarsgard shot onto the scene in a big way this year. He ranked among GQ's Men of the Year 2009, and he was your pick for the year's sexiest star. He's very off the market, though, after going public with his relationship with Kate Bosworth in March. It's Alexander's first time on the PopSugar 100, and not only did he break the top 50, but he's almost 40 spots higher than his girlfriend, Kate.
