When she's on tour, Carrie Underwood needs her space -- especially from Mike Fisher, her husband of nearly two years.

"We see each other as much as we can, but he's not one for road life," the 29-year-old singer tells Vegas magazine's April/May issue. "He can't really sleep on the bus. You can't have a giant bed in the back, so I'm like, 'You're touching me! Go away. What are you doing? Scoot over!'"

Hockey player Fisher, 31, "gets bored," Underwood adds. "I think if he ever comes out with us on tour for any length of time, I'm going to have to find him something to do!"

Underwood is pretty low-key when she hits the road, telling the magazine: "I don't have a chef on tour; I make my own food on the bus."

The "Good Girl" singer does her "own hair and makeup," but she hired a personal trainer to keep her in shape before taking the stage. "I don't take a giant team with me, so I feel like that's the one thing I deserve while I'm on tour: Someone to say, 'Hey, let's go!' and keep me motivated."

Underwood's new album, Blown Away, is available May 1.
