Amy Schumer and Jennifer Lawrence Show Up in Chicago Together at Billy Joel Show [VIDEO]

Who are those two chicks dancing on stage with Billy Joel? Oh, wait...

I'm a huge Billy Joel fan. HUGE. Much to George McIntyre's dismay. So when I saw that Jennifer Lawrence and Amy Schumer got to go up on stage on Thursday night in Chicago, I had a huge case of the jellies.

As in, jealous. To the max.

My sister and I were brought up on Billy Joel. She sent me this text as I was watching the video. But...we're not famous. *sigh*
