Liam Hemsworth has really perfected the art of the sexy smolder. The 26-year-old star has become one of Hollywood's hottest heartthrobs — which, based on his brother Chris Hemsworth's good looks [1], it seems to run in the family. While Liam definitely brought some seriously sexy looks to the big screen with his role in The Hunger Games [2], he's also had plenty of swoon-worthy moments off screen, too, both on the red carpet and in magazines. Take a look at 26 knee-weakening pictures of Liam, then check out his best Instagram snaps [3].
