AceShowbiz - Concertgoers attending Madonna's "Rebel Heart" tour in Inglewood, California on Tuesday, October 27, got special "treatment" when the superstar welcomed singer Katy Perry to join her on stage. During her slightly bizarre guest appearance, Perry was spanked by Madonna.

Perry wowed the crowd at The Forum by joining Madonna for a special rendition of "Rebel Heart" track "Unapologetic Bitch". Together both entertainers sang the track and twerked around. Madonna then unexpectedly began spanking Perry, saying, "She's been a bad, bad, bad girl!" One fan captured the moment in a video and then shared it on Instagram.
