Liam Hemsworth is one sexy Aussie. We first fell for the 28-year-old actor when he starred in The Last Song with his partner, Miley Cyrus [1], in 2010, and we've pretty much been in love ever since. While he certainly knows how to clean up nicely [2] on the red carpet, he's been known to shed his shirt [3] a time or two when he goes surfing. Let's just say Miley is one lucky lady [4]! And good genes certainly run in the family — Liam is the younger brother of Luke and Chris Hemsworth [5]. Grab a tall glass of water and get ready to thirst over these sexy photos.
