Underwood has noted on a number of occasions the pressure she's felt to perform well over the last few months, even if it's just singing in the car or at home. She doesn't want to hurt her little guy's ears.

When asked if her unborn child is a Carrie Underwood fan, however, the singer laughed. "He has no choice," she insisted. "He has absolutely no choice. Number one fan."

The singer and her husband Mike Fisher, who plays in the NHL for the Nashville Predators, announced that they are expecting their first child together back in September. In November they confirmed that the baby is going to be a boy, though they've elected to keep the due date a secret for the time being. At this time, they have yet to agree on a name.

Underwood is expected to give birth to their baby boy this spring.
