Liam Hemsworth in London

Simply put, Liam Hemsworth is a "hot boy." That's how Miley Cyrus describes the Australian actor at least. These two co-starred in the 2009 movie The Last Song.

Prior to this big break in the States, Liam has mostly been known for work Down Under. He starred on show in that country titled "Neighbours" and "The Elephant Princess."

Hemsworth has two brothers, both of whom are also actors.

In the late summer of 2009, rumors began to circulate that Liam was dating Miley. This proved to be the case for a year, until they broke up in August of 2010... and then got back together again a month later.

UPDATE: Liam and Miley continue to be off and on, but the actor received his biggest movie break to date in early 2011. He was named as Gale in The Hunger Games franchise.

UPDATE: Miley and Liam announced their engagement in June 2012! Congrats to the couple!
