Jennifer Lawrence and her boyfriend, Nicholas Hoult, were among royalty at the Amber Lounge fashion show at Le Meridien Beach Plaza Hotel in Monaco this evening. Princess Charlene and Prince Albert II were on hand for the event, which also brought out Vanessa Hudgens. Jennifer and Nicholas made the trip to Monaco after popping up in London earlier this week. The couple strolled the streets together and also stopped by the Duke of York Theatre. Jennifer is gearing up for an exciting Summer, since she's starting filming on the second movie in the Hunger Games franchise, Catching Fire, and she'll celebrate her birthday in August.
