Jennifer Lawrence and Amy Schumer are working together on a screenplay for a comedy.

“We play sisters,” Lawrence told The New York Times about the film’s storyline. “We’re almost done writing. It just flowed out of us. We’ve got about 100 pages right now.”

Lawrence casually broke the news on Wednesday while promoting “The Hunger Games: Mockingjay – Part 2.”

“Amy and I were creatively made for each other,” she told NYT. “We have different flavors. It’s been the most fun experience of my life. We start the day off on the phone, laughing. And then we send each other pages. And we crack up. I’m flying out tomorrow to see her in Chicago. We’ll write a little bit with her sister, Kim, who worked with Amy when she was writing ‘Trainwreck.’”

Lawrence then picked up her phone unexpectedly to text Schumer, who she met just a few months ago, that she spilled the beans about their joint venture.

“Let me just text Amy and tell her that I told you,” she said in the middle of the interview. “I wrote, ‘I just spilled the beans to The New York Times. Is that OK?’” she said. “And Amy wrote back, ‘That you’re gay? Totally! It’s exciting!’”

Schumer wrote the screenplay for her comedy “Trainwreck.” The final installment of Lawrence’s “The Hunger Games” hits theaters on Nov. 20.

They first gave the public a peek inside their blossoming friendship in July when Schumer posted photos of the duo riding a jet ski together.
