Nick Cannon was a guest on Howard Stern's radio show Tuesday morning, and during their conversation, Cannon got a bit personal and spoke about his 2006 relationship with Kim Kardashian and why he ultimately dumped her. Nick says their break up had a lot to do with Kardashian's infamous sex tape with singer Ray-J. 

But it wasn't the tape itself that led Cannon to make his final decision. He says the fact that Kim lied about the tape's existence is what really crossed the line.

"This was my issue," said Cannon. "We talked about this tape...And she told me there was no tape. If she might have been honest with me I might have tried to hold her down and be like 'That was before me' because she is a great girl. She's actually one of the nicest people you'll ever meet. But the fact that she lied and told me that there was no tape?...And I still think she might have even had a part to play with it."

Nick finished by saying "I think she's a great businesswoman if you ask me."
