Christina Aguilera is “comfortable in her skin”.

The 31-year-old Beautiful singer generated headlines for her racy Lotus album cover, in which her hair covers her breasts and her naked body rises out of petals.

If Christina had a say in the matter, she would rather not be fully covered in clothes.

"I like to be free," she revealed on The Ellen DeGeneres Show.

"Sometimes, the less clothing, the better! I""m just comfortable in my skin and my body."

Christina met United States Secretary of State Hillary Clinton when the musician was honoured with the McGovern Award for her work to end world hunger.

The star was enthralled with the politician.

"She""s such a force in a room,” Christina said.

“She""s got that star charisma and everything about her. I couldn""t take my eyes off her, either, so it was mutual. Is that bad? I don""t know. Maybe I shouldn""t say that! I""m so inappropriate."
