Madonna plays off drunk rumors in Instagram post

NEW YORK -- Madonna says she would never perform at a concert "high or drunk" in an Instagram post early Tuesday.

During Madonna's live set, she plays a character who drinks a shot onstage.

She wrote the post in response to a fan who was defending her on Instagram. She told the fan "thanks for supporting me."

Madonna called the claims she was drunk sexist. She wrote: "Sexism is alive and kicking but i am #livingforlove."
