Mariah Carey may call herself a diva, but that doesn't keep her from cookin' in the kitchen!

The American Idol judge got her mix on while preparing her Thanksgiving feast, and of course, Mimi wore a skintight red dress to show off her every curve.

Nick Cannon's 42-year-old wifey was recently seen breaking down during a emotional clip from the upcoming season of AI. Without a doubt, Mimi is going to make for some great TV.

Looking fabulous, girl!
