Nick Cannon and Mariah Carey are no longer a couple; however, it seems there is no bad blood among the exes; in fact, in a recent interview with “The Joe Budden Podcast,” Cannon spoke about one of the biggest lessons he learned from his ex-wife and the mother of two of his children.“Mariah don’t step out the house — it cost her $150,000, $200,000 just to walk out the house,” Cannon said, referring to how the singer accepts jobs with a hefty check. According to Nick, the costs of “everything from security to hair and makeup to jets” should also be included in the contract.The tv host said that when he and Carey began “building a partnership,” he understood why Mariah is one of the highest paid in showbiz.
