Nick Cannon would like to be excluded from Mariah Carey and Bryan Tanaka's narrative. ET sat down with the 36-year-old Wild 'N Out star on Monday, where he commented on the news that his ex-wife, 47-year-old Carey, and Tanaka, her 33-year-old backup dancer, have split. A source close to the former couple tells ET that Carey and Tanaka's relationship has been "tapering off" for a while, and another source close to Tanaka says that he had "long been jealous" of Carey's still-close relationship with Cannon. Cannon said in an interview, "I know nothing about this". Cannon continues to tell ET, "I got too many of my own relationship issues to be worried about an old relationship." As for the notion that Tanaka was jealous of him, Cannon says, "for me, at the end of the day, she's an amazing mother and we focus on our kids. That's never going to change no matter who's in my life or who's in her life."
