Madonna has established herself as a pop music queen and proved that she is one of the best in the business. Because of the reputation she has built though, she doesn’t take any of her work lightly.

The 57-year-old singer is currently performing shows worldwide as part of the concert series.

And it's claimed there is no room for anything less than perfection no matter what the scenario, a strict rule Madonna enforced when one of her dancers turned up tardy.

So when one of her dancers showed up late for rehearsal for her Rebel Heart World Tour stop in New York City, she was sure to let him know who’s the boss!

One of the 'Rebel Heart' hitmaker's crew turned up late to rehearsal and she is such a perfectionist and strict for timekeeping that she reportedly ordered him to apologize in the unusual fashion.

During Madonna’s time in NYC, an insider told NY Daily News that a dancer “was only a few minutes late” to rehearsal and apologized “like crazy,” but that didn’t stop her from ordering him to do something extreme to make up for it: Kiss her feet! The source also said that no one was sure if Madonna was joking. But despite the lack of clarity surrounding the request, the dancer was allegedly quick to drop to his knees and pucker up.

The insider also revealed that Madonna is “a perfectionist,” which means she isn’t going to let much slide. Considering the Rebel Heart World Tour is Madonna’s tenth worldwide tour, it’s no surprise that she’d want everything to be as amazing as possible.

Everyone on her tour is very aware of just how serious Madonna is. They told the New York Daily News' Confidenti@l column: “They know she she's coming because they radio ahead. The first thing that happens is that [organizers] throw out all the water bottles because she can't stand seeing half-empty bottles.

“Then they dim the lights and light candles because she likes the room to look and smell a certain way.”

Madonna's world tour kicked off in September in Montreal, Canada.
