Don’t mess with Madonna.

The singer has hit back at claims that she was intoxicated on stage in Melbourne, Australia, in a personal Instagram message.

Sharing a screen-grab of a fan’s post in her defense, Madonna wrote in the caption, “Thanks for supporting me. Too bad people don’t know the art of acting and playing a character. I could never do any of my shows high or drunk.”

Madonna, who is in the midst of her Rebel Heart tour, echoed recent comments from Jennifer Lawrence and Patricia Arquette, claiming that she would receive more respect if she were a man.

“Underlying all of this is sexism and [misogyny] which proves that not only do we not get equal pay but we are still treated like heretics if we step out of line and think outside the box,” she shared. “Sexism is alive and kicking but I am #livingforlove.”

Madonna’s message is the latest in a string of Instagram posts and public announcements the mother of four has recently made about her personal life. The emotional comments have primarily focused on the strain of her ongoing custody battle with ex-husband Guy Ritchie over their 15-year-old son Rocco, who remains in England with his father.

On March 6, the singer cried while talking about Rocco during a show in Auckland, New Zealand.

She later dedicated her song “Intervention” to Rocco during her clown performance in Melbourne on March 10, which was free for 1,400 fans. Following the show, reports speculated that Madonna may have taken the stage late and drunk.

In response, her rep told PEOPLE that the venue opened later than expected and that the singer “was not drunk, and as promised, she had one cosmo on stage. Nothing more. Nothing less.”

Madonna’s Changing Looks

Madonna’s legal proceedings with Ritchie are expected to continue in England this week. The singer was not present for the most recent hearing, which happened at London’s High Court on Friday.

During the private hearing, her attorney David Williams QC told the court’s family division that “Madonna wants to find a way in which this family can come together to heal the wounds that have been inflicted,” adding, “She very much hopes that the family can start the process of reaching a resolution for the problem.”

Despite a court order for Rocco to return to the U.S. in December, Ritchie has yet to send Rocco to Madonna in New York. For now, Rocco is expected to remain in school in London until a decision is made.
