The gorgeous ladies arrived to the Nokia Theater at L.A. Live rocking nearly identical body-hugging, white cut-out outfits, with Aguilera sporting a low-cut, sleeved Maria Lucia Hohan dress and Richie wearing a sleeveless number by Emilio Pucci.
To complete her look, the Voice judge, who showed off her slimmed-down figure, wore diamond Lorraine Schwartz earrings and red lips, while the former reality star opted for a gold chain link necklace and gold earrings.
So, we want to know…which of these stars rocked their white cutout look the best?
Did Nicole or Christina steal the show?
