How many Grammy 's was Carly Rae Jepsen up for for her song " Call Me Maybe " ?
On August 26 , 2012 , Jepsen performed the song live at the U.S. Open Arthur Ashe Kids ' Day , in what began as a pro-am doubles tennis match ( Mardy Fish and Jepsen vs. Novak Djokovic and Olympic swimmer Missy Franklin ) but quickly became a musical performance initiated by Djokovic and Franklin , with chair umpire Matthew Morrison ( of the TV show " Glee " ) handing a microphone to the seemingly surprised Jepsen .
