Katy Perry joined Madonna on stage at The Forum in Los Angeles on Tuesday during her performance of “Unapologetic Bitch."

Perry was pulled from the crowd and brought to center stage as Madonna and her dancers delivered the final song of the show’s regular set.

Madonna spanked and grinded on Perry as the tune wrapped up, with Katy saying “Thanks, Mom!”

Madonna then thanked her guest and offered her a drink from a banana flask to mark the occasion.

"Sharing a Banana with Katy Perry‼,” posted Madonna after the concert. “Highlight of my show at the Forum!”

"Well, that was unrehearsed," Perry tweeted. "ILY @madonna my QUEEN."

Madonna will wrap up the North American leg of her Rebel Heart tour on October 29 in San Diego, CA. She’ll return to live action in January with dates in Mexico and more US shows.

Earlier this year, “Rebel Heart” debuted at No. 2 on the US Billboard 200 chart with sales of 121,000 copies in its opening week.
