Carrie UnderwoodThe wedding watch is officially on!

The future Mrs. Mike Fisher, a.k.a. Carrie Underwood, tells a Canadian radio station that her hockey-playing fiancé is more involved in the wedding planning than he claims. "He jumps in, and he always says he doesn't. He's like, 'Oh, I don't care. Just whatever you want! But then I go and ask him, 'What do you think about this?' And he'll go, 'Oh, no,' and he'll weigh in. I think he's going to be more involved than he initially thought he wanted to be, which is good. I need help!" (Quote via Dial-Global.)

The high-profile couple will be hitting the gym a lot before their walk down the aisle. Carrie told a Canadian exercise show that she and Mike work out together and plan to teach their kids good, healthy habits.

"Genetics are not exactly on my side," Carrie said. "Once I got out of high school, I packed on about 10 pounds, and once I was on 'American Idol,' I packed on another 10 pounds. I carry all my stress weight -- all my potato chip weight, around my mid-section. You've got to fight genetics sometimes."

Carrie is mindful of her eating habits when she's on tour. "I do not eat catering," she says. "I have a refrigerator on the bus, and when we're in a decent town that has a decent grocery store, I just go and stock up. My off days on the road are spent doing laundry and buying groceries."

At home, Carrie has a personal trainer to keep her in line. "I need it," she admits. "Especially with a tour coming up and a wedding to look good for!"

There's no word yet on a date for Carrie and Mike's "I do"s.
