BEVERLY HILLS — It's not always easy being an Oscar-winner. When Jennifer Lawrence returned to the set of "The Hunger Games: Catching Fire" after winning the best-actress Academy Award for last year's "Silver Linings Playbook," she was treated to a round of applause. Then the teasing began. "I kind of wish just the 'Hunger Games' group didn't know about (the award) because anytime I mess up my lines, Woody (Harrelson) is like, 'Ya better give that Oscar back!'" said Lawrence. "But when I got back, I told everybody that things were going to be very, very different," the actress said, puffing out her chest before bursting into a bout of laughter. "The applause was sweet, but really it was like, 'Let's move on." Returning to theaters Dec. 18, Lawrence will share the screen with veteran actors Robert De Niro and Christian Bale in David O. Russell's 1970s corruption tale "American Hustle." She admits working with the seasoned cast made her nervous. "But Christian is the nicest and made me feel so normal and welcome," said Lawrence. Next up for Lawrence will be appearances in "X-Men: Days of Future Past" and "Dumber and Dumber To." — AP
