A season 14 contestant asked Jennifer Lopez to slow dance while he was auditioning. Jennifer agreed, and the contestant asked the band to play "Stay With Me." Well, fellow judges Harry Connick, Jr and Keith Urban were not content to just sit on the sidelines while JLo got to have all the fun! So Keith picked up a guitar, and Harry sat down at the piano, and they played the song while Jennifer danced with the contestant, who sang along with the song. Looks like such a fun time!
