The rumors are true: Nick Cannon told The Insider With Yahoo yesterday that he and wife Mariah Carey "have been living in separate houses for a few months. ... There is trouble in paradise." He didn't give many more details, other than to deny rumors that he cheated. "My main focus is my kids," he said of the couple's 3-year-old twins. As for Carey, her publicist declined to comment. TMZ reports that, as part of a confidentiality agreement related to their impending divorce, Cannon isn't allowed to say anything about the split unless he wants to be penalized financially—but he is allowed to say they're living apart.
