Britney Wigs Out at K-Fed Party

Either Britney Spears enjoys a good costume party, or she just didn't want to be seen with K-Fed after his Halloween performance.

Though Spears was nowhere to be seen when her husband took the stage last night at the West Hollywood Carnival, Brit was spotted rocking out by herself at an AOL Music party celebrating Federline's album release later that evening.

The pop princess wore a pretty simple outfit to the party, consisting of a bright pink wig and big white sunglasses. We're happy that Brit got into the Halloween spirit, but you'd think a multi-millionaire like her would throw together a better costume.
