Christina Aguilera with Bold New Blunt Bob Hairstyle

Christina Aguilera (29) hasn't had it this short and straight before. Last time she had short hair was in 2004 when she had huge messy curls (see below).

Christina has the perfect face shape (oval) for a bob, but the shortness and bluntness of the cut take a little getting used to. In 2009 she had long, soft, and sexy blonde hair with waves. The extreme makeover completely changed the length, shape, and texture. Now there is a dramatic contrast between her soft facial profile and the sharp ends.

She has worn bold red lipstick for years as her signature style, but with the new haircut it may be time to change her makeup, too.
