Britney Spears, Dancers Get Naked ... Almost

To celebrate their last North American Circus tour performance and punk the singer, Britney Spears' backup dancers took the ringleader's advice and ... got naked!

Well, sorta. As a prank, they stripped down into pink briefs as she performed her hits "Boys" and "If U Seek Amy." Their briefs said "True Brit" on the waistband ...

Britney Spears and her half-naked boy toys rock the house.

Good to see that the gang has a sense of humor and keeps the mood light on stage. We can't wait to see high-maintanence tour continue in Europe.
