At the conclusion of the song, Brooks invited Garrison and her family to hop on his plane and attend a concert he was playing in Nebraska later that night.

Asked how she felt, a stunned Garrison replied, "I don't know yet."

Garrison was nominated for the "Garth Brooks Mother's Day Surprise" by her daughter Brook.

“She was always my backbone. She was always my best friend. She was always there to support me,” she told “Good Morning America."

Before the surprise, Brook delivered a heartfelt thank you to her mother.

“I love you and you’re my best friend, and I just want you to know how much we love you because I feel like you don’t believe us sometimes. You don’t believe what a great mom you are,” she said. “And so this was an ultimate thank you from us kids but also the people that you’ve also become a second mother to. You take care of everyone, and it’s a big thank you from us.”
