Britney performed "Womanizer" at the 2008 Bambi Awards on Thursday in Germany. It's the first big act in her upcoming promotional tour for her new album that comes out on Tuesday, which is also her birthday. It's a big week for Britney who also has her MTV documentary on Sunday, which should give us an inside look on how she prepared for this comeback. We've seen her training in the dance studio a lot so tell us, do you like her first "Womanizer" performance? Love it or Leave it?
