Christina Aguilera may have settled into a cushy position as a judge on NBC's "The Voice," but the 31-year-old singer wasn't always so family-friendly. The former "Mickey Mouse" star appeared alongside Justin Timberlake and Britney Spears as a young teenager in the early '90s and has weathered her fair share of controversies since. Provocative attire? Check. Flubbing the National Anthem? Check. Mysterious, is-that-tanning-spray accidents? Check, check and check.

But one thing's for sure: through it all, Aguilera's biggest offense has always been her astonishing voice. On the weekend before the pop diva drops her seventh studio album, "Lotus," Aguilera has wedged herself firmly into the history of American music and pop culture consciousness more than ever. Take a look through the slideshow below to see the woman better known as Xtina's most outrageous moments.
