CHICAGO, Aug. 28 (UPI) — Actresses Jennifer Lawrence and Amy Schumer made a surprise appearance at a Billy Joel concert Thursday night.
Lawrence, 25, and Schumer, 34 — who wore casual clothes for their Chicago cameo — walked on stage with several others during the singer’s final song: “Uptown Girl.” Eventually, the duo — who recently announced they’re working on a screenplay together — climbed on top of Joel’s piano barefoot and danced.
Witnesses immediately took to social media to report the unforeseen event; Schumer’s colleagues — including her sister Kim Caramele — also posted videos on Instagram.
Joel’s “Uptown Girl” was a prominent tune in Schumer’s screenwriting debut, Trainwreck.
According to reports, the stars and their crews rehearsed all day to get their silly cameos just right.
