Lawrence, 25, who has earned four Globe nominations in the past with two wins, really wants the "Trainwreck" star to take home the trophy this year, reported People magazine.
Schumer, 34, and Lawrence have both received nominations in the Best Actress in a Motion Picture, Musical or Comedy category, for "Trainwreck" and "Joy" respectively.
"That was so amazing because obviously I only pay attention to myself, so I was like oh I got nominated, and then when she texted and said something about the same category I was like - are you, what, like - huh?" Lawrence said.
The "Silver Linings Playbook" actress said she will be voting for Schumer, so that they gain positive publicity for their upcoming film.
"So obviously I'm pulling for her. Selfishly, it would be good for our movie if she won, so vote for Amy.
