Jennifer Lawrence is apparently battling pnuemonia. The Silver Linings Playbook actress admitted she was suffering from the flu on Golden Globes weekend and is apparently still under the weather. Last night, Jennifer's Silver Linings co-star, Jackie Weaver, accepted the AACTA best actress award in LA on Jennifer's behalf. "Poor Jen is really sick," Jackie said as she took the podium. "She really is sick. She has pneumonia." Jennifer, who already picked up a Globes honour for her role in Silver Linings, is also up for a SAG Award this weekend. No word yet on whether she'll be able to attend the show on Sunday, but we're sending Jennifer our wishes for a speedy recovery!
