In an interview with Rolling Stone Magazine, Madge discussed her collaborations with Justin Timberlake on the song "4 Minutes" and with rapper Lil Wayne on "Revolver" which she referred to as "badass".
However, someone the Material Girl wanted to work with didn't accept the offer. That someone was Eminem. "I wanted to work with him, but he didn't want to work with me." Her reason for his decline, "Maybe he's shy."
Too bad Michigan's bad girl and bad boy couldn't come together for what could've been an amazing collaboration.
