Looks like someone mistook Christina Aguilera for Lady Gaga at the 2013 American Music Awards, even though "The Voice" mentor looked very, very un-Gaga-like. In fact, Aguilera looked at her very Xtina-est as she strutted the carpet in a sleek white gown with cutouts on her sides and a slit that went all the way up there on her thigh.
Gaga, on the other hand, rode in on a horse while wearing a long blonde and lavender wig and sporting a lavender Grecian gown. Both ladies looked lovely, but the confusion? Probably not warranted.
