WATCH: Thomas Rhett Stops Show To Deliver Baby News

Thomas Rhett took time out of his concert in Winnipeg on Sunday night to help Tyler and Clarissa Robb find out the sex of their unborn baby.

Clarissa, who is 18 weeks pregnant with the couple's second child, got the country star’s attention by holding up an envelope with pink and blue baby feet on it.

Rhett took the envelope. “You’re putting a lot of pressure on me right here, man, this is scary,” he told the couple, before asking them if they “truly don’t know” what they are having.

He opened the envelope and announced: “It’s a girl.”

The crowd inside Bell MTS Centre erupted in cheers and the singer autographed the card and handed it back to the couple as a souvenir.

Later, Rhett shared video of the special moment on Instagram. “A first in Winnipeg! Congrats on the baby girl y’all,” he captioned it. 

Getting Rhett to reveal the sex of their baby was only fitting considering he’s been a part of the pair’s relationship from the beginning. One of their first dates was at a Rhett concert and his “Die a Happy Man" was their wedding song.

“Thanks to Thomas Rhett for being a solid, stand up guy and taking precious moments out of his show to deliver that news for us,” Tyler wrote on Facebook. “Some how, we're now [even] bigger fans than we [were] before."
