POLL: Christina Aguilera's Monday Looks

For the star unveiling ceremony, the pop star donned a white strapless knee-length dress with leopard print platform pumps. At the premiere in Los Angeles, she opted for a sweeping emerald Elie Saab strapless gown and Neil Lane jewels. Which of Christina's Monday looks do you prefer: day or night?
