Carrie Underwood Dishes On Her 'Toughest Critic' 

"It's still kind of weird, to be honest," Underwood told TODAY on Friday. "Sometimes I'll be with my husband and I'm like, 'I'm going to be a mom. You're going to be a dad. Like, is this real life?' But we're really excited."

The singer is married to Nashville Predators player Mike Fisher, with whom she tied the knot back in 2010. The couple announced their baby news on Twitter Sept. 1, when Underwood decided to play around a little with her dogs Ace and Penny.
