Christina Aguilera blonde tights hat Beverly Hills Lips

Yesterday we snapped pop diva Christina Aguilera arriving at a friend's house in Beverly Hills, and she was rocking a graphic tank with a large set of lips. How appropriate! She may have the voice, but given her dislike for coughing during interviews and other petty things, we know she's got the mouth to match. Hmm, maybe she's just poking fun at herself?
