As Schumer explained Monday night to Stewart, every year she takes a trip gathering all her high school friends together. The stars met in the Hamptons after Schumer asked Lawrence to join the group on a whim.
"So we go to the Hamptons, and Jennifer Lawrence and I have become friends," the Comedy Central star said. "I was like, 'Oh, we're going on a boat tour tomorrow. You should come.' It was kind of a hypothetical, and she was like, 'I think I'm coming!'"
Soon photos of the trip began to surface on Schumer's Instagram account, exciting fans happy to see the two popular actresses together.
The two friends had plenty of fun out on the beach including some wild rides on a jet ski.
"We wound up going jet skiing, and I was like 'I'll drive, I've got this!' And she was like, 'No I'm Hunger Games.'"
Schumer currently stars in the hit movie Trainwreck, while Lawrence's next film is The Hunger Games: Mockingjay - Part 2.
