Carrie Underwood and Mike Fisher look forward to the birth of their first son, even if they can't agree on a name for their little boy.

"He [Mike] keeps trying to push the name 'Bo' for our little guy," noted Underwood during an interview with US 99.5 on Jan. 16. "I just won't have it. Bo Fisher? I don't know. I don't like it. He thinks of it like bow and arrow."

While the parents-to-be struggle to agree on a name, they are also disagreeing over how to decorate their son's room. Underwood wants things to be practical, while husband Mike Fisher has been getting caught up in what looks cool. "We do have a room that's a work in process," she admitted. "It's really overwhelming to go into any baby store."

Underwood made sure to bring her husband along the first time she ever went out to get things for the baby, but even with him by her side it was a daunting task. "There's so much stuff, so many things, and there's really no help. So it's been interesting. It's been a challenge."

In addition to decorating nurseries and fighting over names, Underwood has been busy the last few months starting her own fitness line, Calia, and launching her Dec. 9 album Greatest Hits: Decade 1. She is currently in the process of writing new material, though she has yet to reveal a title or release date.

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