The best thing about this story is that I had actually forgotten that Nick Cannon used to date Kim Kardashian.
Via Contact Music:
The America's Got Talent host began dating Kardashian in September, 2006, but the couple split only four months later and Cannon claims he ended the relationship because she wasn't straight with him about her raunchy past.
The star, who is now married to Mariah Carey, tells U.S. shock jock Howard Stern, "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 (stay with her) 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, (I couldn't get over it.)"
