Nick Cannon, who dated Kim Kardashian back in 2006, revealed the reason behind his breakup with the reality star. Cannon, who is now happily married to Mariah Carey, recently said that the reason he broke up with Kardashian after dating for only 4 months was because of her sex tape.

The 32-year-old radio personality spoke on 'The Howard Stern Show' last week and among the issues he discussed was his breakup with Kardashian. "This was my issue. 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?"

Kim Kardashian famously made a sex tape in 2003 with singer/songwriter Ray J, the brother of award-winning artist Brandy. The tape had thrust Kim into the spotlight - from an unknown girl from California to one of the biggest reality stars today.

Although Kim denies having anything to do with the release of her sex tape with Ray J, Nick Cannon suspects that she might have been involved. "And I still think she might have even had a part to play with [its release]," he said.

Kim's marriage to NBA star Kris Humphries in 2011 only lasted 72 days and is yet to be finalized. She is currently dating Kanye West and while there has been talk as to the pair taking their relationship further, Kim's current marital status is blocking them from doing so.
