Nick Cannon, father of 11 children with six different women, is reportedly making an effort to ensure his twins with ex-wife Mariah Carey, Moroccan and Monroe, have a close bond with their nine half-siblings.

However, sources claim that Carey, 54, is far from pleased with the situation, according to National Enquirer.

Insiders reveal that the renowned singer believes Cannon's approach to fatherhood is "crazy and irresponsible" and expresses concern that her children may not receive the attention they deserve from their father, given his numerous responsibilities.

Cannon, 42, who hosts The Masked Singer, recently took his children with Brittany Bell (35) – Golden (6), Rise (8 months), and Powerful (2) – along with his 11-year-old twins with Carey, to Universal Studios Hollywood. Though the other six children, aged between 3 months and 21 months, did not join the trip, sources suggest that Cannon remains committed to uniting his large family.

Friends and insiders, however, worry that the demands of fatherhood and keeping Carey satisfied may be too much for Cannon, who has struggled with lupus-related kidney disease and was hospitalized with pneumonia in December. A source warns, "He's been told if he doesn't take care of himself, the next big family gathering could be his funeral!"
