Amid Mariah Carey split, Nick Cannon in ‘great mood’ in New York

Carey, 44, and Cannon, 33, have been married for six years.

Fashion shows and DJ gigs are just the remedy for a breakup — if you’re Nick Cannon.

Cannon, in the midst of a split from wife Mariah Carey, was all over Fashion Week and parties this week in New York.

On Monday, he hit up Libertine’s runway show at Lincoln Center, plus a party celebrating NBA star Chris Bosh’s new tie line, Mr. Nice Tie.

Meanwhile, on Sunday, he played a surprise DJ set at The Ainsworth’s NFL kickoff party, where a witness said he was in good spirits.

“Nick was in a great mood and seemed really happy,” the spy dished.

Carey, 44, and Cannon, 33, have been married for six years and have 3-year-old twins, Moroccan and Monroe.
