Trisha Yearwood shares the advice her husband Garth Brooks gave her to deal with nerves

Yearwood opened up on her nerves before hosting "CMA Country Christmas."

But her superstar husband -- seven-time CMA entertainer of the year Garth Brooks -- calmed her fears the morning of the taping with some simple advice.

"I was really nervous and freaking out when I was leaving," Yearwood revealed. "I was saying, 'I don't feel prepared. I'm really nervous about it.'"

"And he said, 'Just go in there and tell them that you're nervous,'" she told ABC Audio. "And I said, 'No, I have to be perfect. I have to go in and pretend everything's perfect!'"

"But the first thing I did was walk in and say, 'I'm really nervous about this,'" Yearwood continued. "And that just kind of lets you take a breath and go, 'Okay, everything's gonna be fine.'"

"He's like, 'You know what you're doing. Don't worry about it. Just let it go,'" she added.

In addition to her hosting duties, Yearwood performs on the show four different times, kicking things off with a big production number built around a medley of "Silver Bells," "Jingle Bell Rock" and "Winter Wonderland."

She also promised to rival other CMA hosts like Reba McEntire and Carrie Underwood when it comes to wardrobe changes.

Lady Antebellum, Chris Janson, Rascal Flatts, Dierks Bentley, Chris Young, Runaway June, Brett Young, Kristin Chenoweth and more join Yearwood for the 2019 edition of "CMA Country Christmas" Tuesday, Dec. 3 starting at 9 p.m. ET on ABC.
