Kim Kardashian, Mariah Carey Beef Over Nick Cannon: Mariah mad at Nick for mentioning ex-lovers 'lady parts'

Mariah Carey says she doesn't even know who her husband, Nick Cannon's famous ex-girlfriend, Kim Kardashian is.

In an interview with Howard Stern on Wednesday, Cannon reveld that he did have a brief relationship with the reality star and his wife has no idea who the "Keeping up with the Kardashians" queen is.

"She doesn't even know who Kim Kardashian is. She doesn't pay attention to that," Cannon admitted, "The world knew these, these weren't like names that, you know, I pulled out of a hat - these are people you've seen me on red carpets with, engaged, in love and all of that stuff, so wasn't like it was new information."

 "You know sometimes, as my wife says, sometimes I should just keep my big mouth shut," He said.

The "America's Got Talent" host revealed that he only mentioned Carey didn't mind that her husband talked about their sexual relationship but didn't like when he mentioned his ex-lovers in the same sentence as her.

"She doesn't care when I talk about our sex life, because our sex life is amazing. She's one of the most beautiful women in the world," he said. "But ... when we bring up -- I'm not gonna do it -- other people's names, she's like, 'Why would you even do that?'"

 "She took it in a way almost as if I was including her in the conversation," he recalled. "We weren't talking about her. The most amazing sex I've ever had is with my wife," he said.
