Christina Aguilera is featured on this year's list of People Magazine's "Most Beautiful.
Christina credits her 15-month-old son Max with allowing her to embrace different aspects of her peronality. She admits, "Being a mom has made me do things I never did before. I'm a total vampire – but Max makes me go out into the sun or to the pool in the middle of the day. He brings out a different side of me that I'm really starting to enjoy."
