Given her back-to-back-to-back Oscar nominations, Jennifer Lawrence has come to be seen as an Academy Awards mainstay. Then why was she a no-show at this week's ceremony? Simple: Work. The 24-year-old actress is filming Joy, her latest film collaboration with director David O. Russell, in snowy Boston. Yes, far, far away from the red carpet and those pesky tripping hazards. Sources have told People that the actress has been using her time in Boston to stay in shape. Lawrence has reportedly been taking Flywheel classes at the Shops at Prudential Center. "She comes in after the lights go down, and sneaks out before they go on," one Flywheel regular told the magazine. The Kentucky native was also spied shopping at the mall on Oscar Sunday. She and a bodyguard were also photographed walking around the Back Bay neighborhood. Lawrence was decked out in winter gear and clutching her small dog, Pippi. It's not quite as glam as, say, rubbing shoulders with Channing Tatum or scoring a Lego Oscar, but the girl's earned a break.
