Carrie Underwood not only has a great family, but a great sense of humor. She shared this tweet about how her son called her "Carefree Underwear".
The comments from fans are hilarious!
The name has sparked so many comments that it might be a great brand idea. Carrie Underwood does have a workout clothing line, Calia, and Carefree Underwear doesn't sound as sexy. But it sure would get people talking.
