Pregnant Carrie Underwood Wants To Wait To Learn Baby's Gender; 'Something In The Water' Singer Calls CMA Co-host Brad Paisley A 'Blabber Mouth'

It can be revealed that the now pregnant Carrie Underwood did not know the baby's gender up until they left the doctor's office and went to a nicer setting. Meanwhile, the "Something in the Water" singer called CMA co-host Brad Paisley as a "blabber mouth."

In an interview with KTIC Radio, as shared by Taste of Country magazine, a pregnant Carrie Underwood told the host that she and husband Mike Fisher went to the doctor's office to learn of the baby's gender.

"It's kind of a sterile place. We got to see all the pictures and everything. It was really cool to see that, but whenever she'd get near ... near those parts ... we would look away," she said.

So Carrie Underwood and husband Mike Fisher took the sealed envelop with them revealing the baby's gender and opened it at the restaurant during dinner.

"[It was] just the two of us in a nicer setting, but we both knew. So, that was just confirming our suspicions. We didn't really speak of it before, 'cause we were both just like, 'Whatever. It's all good.' But we knew it was a boy," she said, according to ABC News.

However, it's not that much of a secret anymore as her CMA Awards co-host Brad Paisley outed Carrie Underwood's baby gender during the televised event.

During their spiel about the living legend, Garth Brooks, Brad told Carrie: "Hey, you can name him Garth."

He quickly added, "Hashtag: Blew it."

Carrie Underwood claimed that she planned to announce the baby's gender during the event but Brad Paisley spoiled her plans.

"Brad's got loose lips. He's a blabber mouth! So, I was like, 'I'm not gonna tell you until we're ready for the rest of the world to know, 'cause I know you'll tell people.'"

During the CMA Awards, the very pregnant Carrie Underwood didn't let her baby bump get in the way of her tradition as she had 11 wardrobe changes during the show.
