Lily Allen - Alfie Allen

Many don't recognize the connection between Theon Greyjoy (Game of Thrones) and musician Lily Allen. They're brother and sister!

Alfie Allen's character had a rough go of it in season three of the HBO series. But at least the suffering was fictional, unlike when his older sister dropped this less-than-flattering single about him in 2007. Alfie peaked at 15 on the UK singles chart.
