The 28-year-old may be a big star, but she says she doesn't see herself as much of a celebrity.
Speaking to reporters in Los Angeles while promoting her debut film Soul Surfer, she said: 'When I'm on stage, I feel like a performer, and I know people are looking at me and taking pictures and all that stuff, and they're singing along.
'That part is wonderful, but I do live in Nashville. I live the most boring life away from what you see me on camera doing.
'I never go out to eat. I never do anything. I think that is why I consider myself not a celebrity [sic]. I'm a normal person who sings on stage.'
And the Grammy Award-winning artist admits she enjoys her low-key lifestyle.
She said: '[Most] of the year… I'm a lover to my doggies, I'm a maid, [and] I clean the house. Me as Carrie the person wanders around in sweatpants. But when I have to look like Carrie Underwood, I look like this.'
