Christina Aguilera likes to go commando, and she's comfortable telling Chelsea Handler all about it.

While appearing on Chelsea Lately, Xtina tells the talk show host, "I don't wear underwear. I like to be as free as possible at all times. It’s just who I am. It's empowering. It's p***y power!"

To make The Voice mentor feel comfortable, Chelsea ditched her pants for the segment. Loves it!
