Eminem Passed on Madonna Collaboration

Madonna is one of the biggest music artists in the world, yet apparently she can't nab any collaboration she wants.

According Rolling Stone, the icon of single-name status said Slim Shady turned down a request to work together.

"I wanted to work with Eminem. I don't think he wanted to work with me." the singer said in the new issue. "Maybe he's shy."

It's unclear when Madonna's attempt to work with hip-hop's great white hype went down.
