VIDEO : Jennifer Lawrence and Amy Schumer Dance on Billy Joel's Piano

Jennifer Lawrence, Amy Schumer and Billy Joel came together for an unforgettable moment in Chicago last night, when the legendary performer?s record-busting tour stopped at Wrigley Field. During a rendition of Joel?s 1983 hit ?Uptown Girl,? Lawrence and Schumer shimmied from the side of stage to the top of his grand piano, where they danced barefoot like no-one was watching. Many thousands were. In a video taken before the concert, the Oscar winner and the comedian rehearsed their routine with Billy in an empty Wrigley Field in the leadup to the big show. If Schumer and Lawrence look like a sister act, that?s because they?ve jointly written a comedic screenplay in which they plan to co-star as siblings.
