Mariah Carey and Nick Cannon are allegedly fighting over custody of their eight dogs following their split.

The former couple, who called time on their marriage in August, are reportedly locked in a bitter battle over who will have legal guardianship over their four-legged friends, The Good Reverend Pow Jackson, Mutley P Gore Jackson The Third, Jill E Beans, Pipitty Jackson, Cha, Jackie Lambchops, JJ and Speak E Beans, according to the Sunday Express newspaper.

The pair, who also have three-year-old twins Moroccan and Monroe together, have reportedly settled their £325 million fortune via their prenuptial agreement.

The 'America's Got Talent' host, 34, who married Mariah in 2008, has been throwing himself into his work since the split because making other people happy brightens up his day and hides his own issues.

He said recently: ''That's why we all entertain, to put a smile on others' faces. I take that as a lifelong goal, but still, at the same time, take it one day at a time.''

Meanwhile, it is not known why the duo ended their marriage after six years, but rumours suggest the hunky star had cheated on the 'Hero' hitmaker.

However, Nick claimed in August that infidelity had nothing to do with their break-up and insisted their main focus is, and always will be, on their children.
