Nick Cannon has admitted his marriage to Mariah Carey is on the rocks. Nick confirmed the rumors telling The Insider that "there is trouble in paradise. We have been living in separate houses for a few months." Last night TMZ reported that the divorce lawyers are already hammering out a settlement. Nick stayed tight-lipped on what caused the split, but denied cheating was to blame. He added, "My main focus is my kids." The couple, who are parents to three-year-old twins, wed in 2008 and even celebrated their sixth wedding anniversary in April.
