Material Girl! Madonna Acted Like A Diva On The Set Of 'Will & Grace,' Producer Reveals, Insisted On Wearing Her Own Clothes

Madonna started drama behind the scenes of Will & Grace after refusing to wear costumes provided for her character, claims producer Gary Janetti.

The “Material Girl” singer appeared in one episode of hit sitcom in 2003. She was cast as playing the role of Liz, roommate of Karen, played by actress Megan Mullally.

Trouble allegedly ensued when the blonde babe was dissatisfied with wardrobe options for Liz and insisted on wearing her own clothes instead. “(She's) like an executive secretary, the kind of woman who wears her sneakers on the subway and carries her shoes in her bag and goes to a happy hour after work,” explained Janetti on the role of Liz during his appearance on the podcast "Behind The Velvet Rope" with David Yontef.

“So she was supposed to wear, you know, Anne Klein II suits with sneakers and be the kind of woman you'd see on the subway. And Madonna as that is very funny.” The producer explained his vision of the episode, highlighting the comical personality differences that Madonna would bring to the character.

However, this was apparently not being seen eye-to-eye between the Madonna and producer at the time of shooting.

“But Madonna didn't want to wear any of those clothes so she wears very long blonde hair extensions and these outfits. So, she looked fabulous, but as a result, it was about 50 percent less funny than it should have been.”

The eccentric icon even went as far as taking matters in her own hands to ensure her wardrobe demands would be met — she showed up to set with her own glam team and wardrobe. Given her success at the time, Janetti's crew understood that attempting to pursue Madonna into the original Liz outfits “wasn't a conversation that was going to happen."

Since Madonna's style has always been eclectic, Janetti said they mulled over changing her outfits.

“We even had jokes we had to change because of what Karen said — maybe based on what she was wearing — (because it) didn't make sense anymore,” Janetti said. “I mean, she looked like Madonna. She looked like a rich, fabulous celebrity, which wasn't what the character was.”

Even with the overstep of authority by the pop singer, the episode was deemed a success, albeit not without plot changes and headaches.

“But she was game when she was on the show, and she was also funny," Janetti said as he ended the story on a lighthearted note.
