Nick Cannon has reportedly claimed he "walked out" on his and Mariah Carey's marriage.
The 'America's Got Talent' host allegedly ended their relationship as he's concerned about the 44-year-old singer's "emotional state" and is worried about their three-year-old twins Monroe and Moroccan's welfare.
A source told TMZ.com: "He wants to create an environment separate from Mariah that gives the kids a safe haven from the chaos at her home."
Friends also claim the 33-year-old hunk believes Mariah's management are not providing her with the support she needs and only care about her ability to "make money and pay their salaries."
Nick confirmed earlier this week he and Mariah - who married in 2008 - have been living in separate houses for a "few months" after their relationship hit the rocks.
He added: "My main focus is my kids."
It was previously reported Mariah's trust issues played a role in the split as she believed her spouse might have cheated on her whilst he was away working.
However, Nick has since denied that infidelity had anything thing to do with the break-up.
Meanwhile, Mariah and Nick are reportedly currently in talks with their lawyers over a custody agreement for their children, as well as a property settlement.
