Nick Cannon has praised his wife Mariah Carey as ''awesome'' and joked he has nicknamed her ''Dr. Carey'' because of her ''nurturing'' personality.
The 'America's Got Talent' presenter - who was recently diagnosed with an autoimmune disease which sees his immune system attack healthy cells, tissue and organs - explained he has dubbed the 'Hero' hitmaker ''Dr. Carey'' because of her ''nurturing'' personality.
He said: ''She's awesome. She's so nurturing. I call her Dr. Carey. She just takes care of me and makes sure I'm eating what I'm supposed to be eating.
''She made me an egg-white sandwich before I left the house this morning. Those are the things I have to be eating now, no more bacon. She takes care of me.''
Nick - who has 11-month-old twins Moroccan and Monroe with Mariah - admitted his children are his ''motivation'' for living a healthy life.
In an interview with 'Good Morning America', he added: ''In the hospital, that's the first thing that comes to your mind. I have to be around for my children and I have to be healthy for my children, so they're the motivation for the whole thing.
''I scared a lot of people. I scared myself.''
Nick is now under strict doctor's orders to get plenty of rest and eat healthily.
He explained: ''I have been ordered to sleep at least six hours a night. They say rest is probably the best medicine. I'm dealing with it.
''The diet is the worst part. I can't have any fast food anymore ... no Happy Meals, nothing.''
