madonna bad girl
Once upon a time, this "Bad Girl" was a sex symbol with concerts so racy that they landed her on the Pope's naughty list. What else? Oh, just her X-rated picture book, "Sex," her lip lock with Britney at the 2003 MTV Video Music Awards, and the time she dropped 13 F-bombs on "Letterman." Madonna hasn't completely mellowed out, but she's gone from a bad girl to a mother of four, a dedicated Kabbalist and a yoga devotee.
