Brad Paisley stole the show at the CMA Awards in November when he revealed the gender of Carrie Underwood's baby.

Recently Paisley dished on how they came up with the great idea to announce it on live television. Underwood and her husband, NHL player Mike Fisher, want to keep the due date private, but had no problem with the gender being announcing onstage.

"We started brainstorming about the awards show…" explained Paisley in an interview with Country Countdown USA on Sunday. "Somewhere it came up. It was like, 'We could reveal it on the show, if you're gonna reveal it anyway.' And she said okay."

Underwood knew for weeks before the CMA Awards that she was having a boy, but Paisley suggested she keep it quiet if they were going to use it for the show. "I told her not to tell anybody until that night…" said Paisley. "She asked me, 'When do you want to know?' And I said, "Right before we walk out.'"

As it turns out, making the announcement became a pretty big deal. Paisley had already guessed it was going to be a boy based on how the singer had begun to act around his sons, but when they got onstage and told people the reaction was a little guarded.

"The funny part was people didn't know if we were serious," declared Paisley. "They were texting her publicist if it was true, and they didn't know either. It was a great way to do it. I love anything you can do with a joke attached."

The Something In The Water singer also happens to be a big fan of unique announcements. On Sept. 1 she used a photograph of her dogs with big brother and big sister t-shirts to reveal that she was pregnant.

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