Pregnant Carrie Underwood and husband Mike Fisher couldn't seem to agree on the name for their baby boy as the "Something in the Water" singer is overwhelmed by all the things they need to buy for their kid.

In a radio interview with CBS Local, she said her husband has been pushing her to name their boy "Bo."

"I just won't have it. Bo Fisher? I don't know. I don't like it. He thinks of it like a bow and arrow," she said.

In an earlier interview with Today Show, pregnant Carrie Underwood also claimed she and husband Mike Fisher have some baby names in mind.

"There's kind of a couple [of names] that we're okay with, but it's hard, labeling your child for the rest of its life. I was like, 'Why don't we come up with a short list we're both agreeable to and then meet the little guy and see what we're feeling,'" Carrie Underwood explained.

On Sept. 2, Mike Fisher tweeted: "We haven't picked names yet but it's looking like Fly is gonna fly. #boyorgirl #flyfisher."

Carrie Underwood also claimed that being pregnant still take a little getting used to.

"I'll just walk by a mirror, and I'll just ... I forget [that I'm pregnant] and then I'll see myself and I just start laughing.... My body's not mine right now," the former "American Idol" said.

Meanwhile, in the same radio interview with CBS, Grammy winner Carrie Underwood claimed that decorating the room of their baby has been harder than expected.

"(Mike) saw this car bed thing for a baby, and I was like, 'We're not getting one of those!' He's going to get a crib. We do have a room that's a work in progress...It's really overwhelming to go into any baby store," she explained.

Pregnant Carrie Underwood added, "The first time I went, I made Mike go with me because I knew it was overwhelming, and I wanted him to see it all and take it al in. Because there's so much stuff, so many things, and there's really no help. So it's been interesting. It's been a challenge."
