Yesterday was a very big day (and night) for Christina Aguilera. She received a star on the notorious Hollywood Walk of Fame in the morning, and she premiered her film debut in Burlesque at night.
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?
