Jennifer Lopez nailed winter fashion at the London photocall for her film “Unstoppable.” The actor and singer flaunted a sophisticated Christian Dior ensemble while attending the event on 7. Her outfit included a sharp and classic double-breasted coat in white and black turtleneck and hat that provided a well contrast to the look.

After taking to the red carpet in a ladylike Dior ensemble yesterday, Jennifer Lopez couldn’t help but get a little “loud” later that evening. The singer and actress was spotted returning to her London hotel in head-to-toe cheetah print—a far cry from the demure coat dress and top hat she wore earlier in the day.
