Mariah Carey likes to dress down at home.

Although the 'American Idol' judge is always immaculate in her public appearances, she likes nothing more than to relax with no makeup when she is at home with her husband Nick Cannon and 22-month-old twins Moroccan and Monroe.

Nick told In Touch magazine: ''She doesn't ever wear that much make-up on TV - it's all about the hair for her.

''But at home, she's always chilling with no makeup and her hair tied up. I mean you can't be dolled up 24/7. Besides she's my wife, she really doesn't need to be dolled up for me.''

The 'America's Got Talent' host has previously insisted that, despite his wife's diva reputation, she is just a normal wife and mother at home.

He said: ''She does everything everyone else does.

''You can definitely have a family of two people, but when you create humans together, it changes things. It's brought us even closer together. Being parents creates a whole different dynamic; you make different decisions. But it really solidifies what a family is all about.''
