Footage from the concert shows the stars — who shared an epic run-in at the Hamptons last month — joining Joel, 66, during his spirited performance of his 1983 smash single. Schumer, 34, clad in a black tank and matching pants, stormed the stage with her new BFF Lawrence, 25, who looked cute in distressed denim and a breezy white top.

Their latest antics came one day after Lawrence confirmed to the New York Times that she and Schumer are working on a screenplay together. “We play sisters. We’re almost done writing,” the Oscar winner dished. “It just flowed out of us. We’ve got about 100 pages right now.”

Lawrence also revealed that their friendship is very new. “I emailed her after I saw Trainwreck and said, ‘I don’t know where to get started. I guess I should just say it: I’m in love with you,'” the Hunger Games actress said of meeting Schumer a couple of months ago. “We started emailing, and then emailing turned to texting.”
