Billy Joel is taking a page out of Taylor Swift’s playbook by inviting some famous friends onstage during his latest show. But these were no ordinary famous faces – they were Amy Schumer and Jennifer Lawrence.

Schumer and Lawrence joined Joel for his song “Uptown Girl" at Chicago’s Wrigley Field on Thursday night, with the famous duo dancing on top of his piano.

Chicago Tribune reports Inside Amy Schumer writer Kyle Dunnigan also joined them onstage, and foreshadowed what was to come on Instagram when he posted a video of them rehearsing earlier in the day. He has since deleted it.

As we previously reported, Lawrence spilled the beans to the New York Times that the new friends are writing a screenplay together, in which they play sisters.

“It just flowed out of us," Lawrence confessed. "Amy and I were creatively made for each other. We have different flavors.”

She also revealed they would be in Chicago together, saying “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.”
