Carrie Underwood trusts her husband completely.

The country singer married hockey player Mike Fisher in 2010 and although they often lead separate lives because of work, Carrie knows Mike would never cheat on her.

She told Glamour magazine: "We're both independent people, so we can't have somebody around 24 hours a day, seven days a week. The drawback is that we can go weeks without seeing each other. But he's the only guy I've never had to worry about. Any guy I've ever dated, there would always be that doubt: 'He didn't answer his phone. What's he doing? It's late.' I'm not the crazy-girlfriend type, but there was a little voice in the back of my head. I don't have to worry about Mike. I don't think twice. He's going out? I don't care; it doesn't bother me. I don't bat an eye."

Although Carrie, 29, says the simple things in life make her happy, she admitted she happily passed over the job of paying her bills to her business manager because she hates it.

She explained: "I love to be at the grocery store. It makes me happy to have a full fridge and a full pantry. I hate sending my laundry out. I don't like the thought of other people washing my clothes. What am I happy not doing? Lawn care. And I have a business manager who pays my bills. I did all that myself in college, but I only had one credit card back then."
