Rita Ora and Madonna arrive at The Metropolitan Museum of Art's Costume Institute benefit gala celebrating "China: Through the Looking Glass" on Monday, May 4, 2015, in New York.

It's not the 1989 Tour, but Madonna's Rebel Heart jaunt has featured its fair share of surprise guests from Katy Perry to Anderson Cooper, all of whom have been spanked and presented with a banana during Madge's "Unapologetic Bitch."

Last night in Berlin, Rita Ora added her name to that growing list, taking the stage with Madge for an ass paddling and complementary phallic fruit.

"Blondes have more fun in Berlin! Sexy Bitch Rita Ora" Madonna wrote on Instagram after the show. On her Insta, Ora shared a pic of her and the Queen flipping the bird to the crowd.

Along with Perry, Diplo, Chris Rock and many others, Ora popped up in Madonna's whirlwind "Bitch I'm Madonna" video earlier this year.
