Nick Cannon is suing mad at Mariah Carey ‘s business manager Michael Kane–after Kane sold their home without Cannon’s knowledge! The America’s Got Talent host has filed a lawsuit against Kane over the sale of his and Carey’s $9 million Bel-Air home. The 6-bedroom, 9-bath property was originally listed for $12,995,000 million. The docs also claim Cannon “has yet to see the estimated settlement agreement nor has he been provided with any information about required closing costs and loan payoffs, and other planned disbursements from escrow.”
