Underwood, 29, said she even likes to indulge herself on the grocery shopping, reported People magazine.
"It makes tour life a little difficult because those are things that I really don't have time to do. So that's what I do on my days off. We go to the laundromat. I get my quarters, we go to the laundromat and go do our laundry. I just don't like other people doing my laundry. It freaks me out," she said.
Underwood, who tied the knot with hockey player Mike Fisher in 2010, said it took her a while to adjust with her married life.
"At first it was weird. Sometimes I still have those moments where I can't believe I'm married. I spent 27 years not being married and I kinda got used to it."
