‘Will & Grace’ Set: Madonna Mania

The behind-the-scenes mayhem during Madonna’s taping of ‘Will & Grace’ was so wild that when the Material Girl made her guest appearance, series co-star Megan Mullally had to tell the crowd to keep it down so they could get through the taping. “Just try not to applaud,” said Megan. “When I’m funny, applaud,” added Madonna. Madonna admitted she had never seen the show and finally agreed to appear after watching tapes of the NBC series. “We’d rehearse and rehearse and I had everything memorized and then they would come out with these really long things and I’d just think ‘I’m never gonna remember it,’” Madonna told Access Hollywood.
