Madonna makes a rare television appearance on her good friend Jerry Seinfeld’s show The Marriage Ref tonight on NBC at 10p. Not only is the twice divorced musician a panelist on the show, so is the hysterical and happily married Ricky Gervais. The host of the show, Tom Papa was on Jimmy Kimmel Live yesterday and he told him that during tonight’s TMR he had to yell at the singer, “Not now Madonna! You behave yourself.” I can’t wait to see what she did to warrant that type of response. Should be an interesting episode, so check it out on NBC at 10p.
