Nick Cannon is starting to panic!
The 35-year-old doesn't want his ex-wife Mariah Carey to marry her new boyfriend James Packer – so much so that he begged her not to.
"Nick is begging Mariah not to marry James," an insider tells In Touch Weekly. "He loves the co-parenting [to twins Moroccan and Monroe, 4] groove they've been in and he's worried that might change if she gets married to someone else."
"He likes being the only man in Mariah's life. Friends even think he would get back together with her if he had the chance," they added.
