Madonna left The Tonight Show viewers cringing as she flashed her bottom and gyrated on Jimmy Fallon’s desk during a ‘trainwreck’ interview on Thursday. The singer, 63, appeared on the show to plug her Madame X documentary, but left the host astounded when she soon rose from her seat and slid herself across his desk. The bizarre segment began when Jimmy asked Madonna what she hoped viewers would get from her film, to which she responded: ‘Art is important in our lives. I don’t think people emphasize that enough. I’m really inspired by James Baldwin, the writer.’
