Christina Aguilera buys lingerie instead of pants

Christina Aguilera headed to Agent Provocateur yesterday to shop for lingerie with a friend. But Page Six thinks she would have been better off heading to buy some pants. Aguilera's outfit was clearly missing something -- a bottom. No, Aguilera, tights do not count.

This is the fourth time Aguilera has been seen in public without pants in a span of two weeks. On Monday night, she went to dinner at Off Vine in Hollywood with her boyfriend Matthew Rutler and wore a Andy Warhol t-shirt that ended right at her crotch with nothing but fishnet stockings.
