In Brave and the Bold # 33, Wonder Woman, Batgirl and Zatanna danced to Beyonce's "Single Ladies" Song. It is also rumored to make an appearance in Wonder Woman's TV show. So, although Wonder Woman writers attribute the "Single Ladies" song to her, I disagree.
I think " I Don't Need A Man" by the Pussycat Dolls suits her personality more. What song do you think defines Wonder Woman best?
