Christina Aguilera doesn't just have an aversion to pants ... she also doesn't wear underwear!
The pop star/"Voice" mentor was a guest on "Chelsea Lately" last night, where she made a very risque admission.
"I don't like to wear underwear," says Xtina. "I like to be as free as possible at all times. It’s just who I am.” TMI alert, right?!
The singer has caught a lot of flack from Chelsea Handler in the past for her risque attire, which usually brings a lot of attention to her chest.
Before agreeing to be on the interview, Aguilera made Chelsea dress up like her to make up for making fun of her.
