1. Liam Hemsworth

Well-muscled Aussie actor Liam Hemsworth reportedly stepped out on his on-again, off-again leading lady Miley Cyrus. The other woman in this too-hot-to-handle love triangle was none other than Betty Draper. More accurately, it was blond bombshell January Jones, who portrays the icy Mrs. Draper on AMC's Mad Men.

Jones, for her part, thought the Hunger Games star was single at the time.
