Nick Cannon Steps Out with New Lady; Mariah’s Friends Concerned about Mental Health

*Well that was fast.

In the midst of his split from wife Mariah Carey, Radar Online is reporting that Nick Cannon attended the launch of Chris and Adrienne Bosh‘s new tie line, Mr. Nice Tie, in New York City on Wednesday with singer-songwriter Kreesha Turner, 29.

They were also spotted together at New York Fashion Week, attending the Falguni and Shane Peacock runway show.

Meanwhile, Life & Style is reporting that Mariah’s friends are worried about her state of mind as she deals with her divorce.

“She has a history of mental health issues,” an insider tells the magazine, referring to Mariah’s 2001 stay in a hospital for psychiatric care.

Another source tells Life & Style that Nick wanted to leave Mariah months ago but was fearful she’d have a meltdown if he ended things.

“Nick’s No. 1 goal is to get the kids into a healthy environment where they would have some sense of normalcy,” an insider adds.
