The Silver Linings Playbook star – who’s nominated for her role as troubled girl-next-door Tiffany – is currently very sick, a source tells PEOPLE.
But that didn’t stop the 22-year-old actress from stopping to chat with E! News.
“I’m fine, I’m fine,” Lawrence told Giuliana Rancic. “I’m so worried everyone’s, like, scared of me like, ‘Are you still sick?’ No, I’m fine.”
Showing off her Dior gown and Chopard jewels, Lawrence continued to joke with Rancic, saying,”I have walking pneumonia and it’s highly contagious!”
