Madonna has been on her Rebel Heart Tour for most of 2015 with a string of successful performances. At least until her gig on Thursday Dec. 14, which was an absolute disaster. She arrived onstage about 50 minutes after the show was scheduled to begin and fans booed her and angry concert-goers unleashed a string of tweets about her tardiness.

Billboard reported she tried to reason with fans in a video that has since been removed, saying, "Thank you all of waiting. I don't like to be late, by the way, and all you b*tches who keep complaining about it can shut the f*ck up. I'm not back there eating chocolates and filing my nails and getting my extensions done."

She further says in the video, "The background video crashed. We had no video... we had to wait until we could reboot it. No selfish diva b*tch reason. If you diva b*tches to keep complaining about it, don't come to my show."

But fans booing her is not the only notable occurrence that has happened on her nearly year-long tour in support of her album by the same name. The tour has featured many big names, including Diplo, Amy Schumer, Anderson Cooper and Katy Perry, who ended up grinding with Madonna during their joint performance.

The dirty dancing took place during the duo's rendition of "Unapologetic B*tch," where Madonna gathered her dancers around Perry so that they could spank the fellow pop-star and refer to her as a "bad, bad girl." Perry was also crowned the "unapologetic b*tch" of the night after their performance.
