Okay, maybe she just couldn't help herself. The voice judge / singer Christina Aguilera is let it all hang out while performing to Etta James' trademark song, "At Last", at the music legend's funeral on Saturday. Even at a first glance, Aguilera's outfit seemed funeral-appropriate. Aguilera wore a black suit with plain black heels. But look again! The jacket to her suit had a cleavage-baring design more appropriate for a nightclub! And we have the photos to show.
