Carrie Underwood's 5 Must-Haves on Tour

Country superstar Carrie Underwood talked with “Nightline” about her marriage to hockey player Mike Fisher, her feelings on having children, and the things she absolutely must have when she goes on the road.

1. Her Dogs

Underwood never travels without her canine companions, Ace and Penny. “They're with me everywhere,” she said. “I couldn't imagine not having that little piece of home with me everywhere I go.”

2. A Fully-Stocked Refrigerator

Carrie likes to cook her own food rather than eat out. “I bring pots and pans and little burners and things like that so I can cook food while I'm on the bus,” the singer explained. “I'm always buying groceries on my days off.”

3. Her Personal Trainer

“I do my own hair and make-up on tour, so I feel like I… deserve to have someone motivating me, helping me be the best that I can be physically so I can get through the rigorous tour.”

4. Lots of Movies and Shows on DVD

“There is a lot of time to kill on the bus.”

5. A New Down-Alternative Comforter

Underwood said she buys a new comforter every time she goes on tour, “just to make sure my bed is super comfy and doesn't feel like a hotel bed.”
