Jennifer Lawrence tells ET that she is rooting for BFF Amy Schumer to take home a statuette at the Golden Globe Awards next month, despite being nominated in the same category.

"We both agree. We want her up there," Lawrence said while promoting her upcoming movie, Joy. "Although she won't say that, I can say it."

Previously, Lawrence took home back-to-back Golden Globe awards in 2013 and 2014 for her starring role in Silver Linings Playbook and her supporting work in American Hustle.

"I was like, 'I want to see your sweet little ass up there on that stage,'" the Oscar winner shared. "Selfishly, it would be really good for our movie if she won. So vote for Amy."

Lawrence, 25, and Schumer, 34, are co-writing a screenplay in which they'll star as sisters. Schumer has described the script as "funny," "dirty" and "real."

When ET caught up with Schumer last week about her big nomination, the Trainwreck star told us that she got the news when she was "in bed alone," and that she was greeted with champagne when she arrived to work on her Comedy Central sketch show, Inside Amy Schumer, later that day. Lawrence had a similar experience.

"I was drunk in bed too," Lawrence said. "I actually sent her a selfie of me in bed with wine before we knew about it."

Always the jokester, Schumer quipped at the time of her nomination that, despite their friendship, it's every woman for herself.
