The happiest place on Earth got an extra dose of star power this weekend! Held at Disneyland in Anaheim, California, celebrities like Natalie Portman (in Louis Vuitton), Angelina Jolie (in Saint Laurent Paris), and Kristen Bell stepped out at Disney's D23 Expo to talk about their much-anticipated projects. Bell and her co-star, Broadway actress Idina Menzel, got animated about their upcoming film Frozen, which is loosely based on Hans Christian Andersen's story The Snow Queen, while Portman and Tom Hiddleston attended a panel for Thor: The Dark World. However, one of the most unexpected moments was when Angelina Jolie surprised the crowd to speak about her upcoming role in Maleficent, which follows the storyline of Disney's Sleeping Beauty from the villainess' point of view. "Since I was a little girl, Maleficent was always my favorite," Jolie told her fans. "I was terrified of her, but I was always drawn to her." The feeling is mutual!
