Is Madonna having a meltdown?

The 57-year-old singer was nearly 3 hours late to her Nashville concert on Jan. 18, and she did not give a reason or an apology.

Currently, Madonna is in a custody battle with ex Guy Ritchie over their 15-year-old son Rocco. Rocco is living with his father and refuses to go back to the United States. Madonna and Ritchie are due for a court hearing in New York on February 3.

But Madonna' personal stress aside, even country artist Reba McEntire, who was in the audience, could not believe Madonna's tardiness. She was supposed to perform at 8 p.m. but didn't start until 10:31 p.m., as Reba pointed out.

"At the Madonna concert. She's not on yet...really?" Reba captioned the first of three Instagrams while waiting at Bridgestone Arena.

Twitter users at the concert weren't happy. "@Madonna still hasn't taken the stage. She is over two hours late ... on a week night. #Nashville #Madonna," one wrote. "Come on @Madonna ...you're late again!!! #Nashville Put on your cowboy hat and let's start this show!!! #rebelheart," another tweeted.

This late-show comes just days after Madonna was accused of being drunk at her show in Louisville, Kentucky. She also showed up over two hours late too.

On Jan. 17, she addressed the drinking on Instagram, "Working on my stand up laying down. Good practice!!! 👍🏻Thanks Louisville! 😂 the tears of a clown soon to follow the ️#rebelheartour and for those people who like to believe all they read i never drink and perform!!! My show is 2 hours and 15 minutes of non stop singing and dancing," she wrote. "In Louisville I made a joke about doing a stand comedy act dressed as a clown and being able to drink alcohol. Its so very interesting how society continues to not only treat me in a totally sexist way (if i a were a man no one would have said a thing) and also continue to take everything i say literally!Thats what happens when people don't read books and get all information from TMZ."

You could say that Madge is just being "unapologetic!"
