christina aguilera lady gaga amas 2013 Christina Aguilera mistaken for Lady Gaga on AMAs 2013 red carpet

Umm, whoops?

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.

Could you see any Gaga in Aguilera’s AMAs outfit?
