And though some attendees captured the romantic moment on video, Mock and Booth had trouble remembering exactly what happened during the proposal. In a previously shared Instagram Story, Booth joked that both she and Mock "blacked out" because of the intensity of the moment. "We *think* he said 'Sorry BIP didn't work out for you. I'm glad you came back to Nashville to me? Something or other. I wanna spend the rest of my life with you? Got down on one knee—Will you marry me?'" she recalled.

"I knew that he was going to propose eventually and we were going to be married and live happily ever after," she wrote in the Story. "I just didn't know it was going to be that soon. He had been like trying to throw me off which now makes sense." "He was saying like, 'Yeah, it will happen, maybe like by the end of the year' so I did not suspect it all," Booth continued "I thought I was going to be giving out like a date card on The Bachelor live show thing and it turns out I wasn't at all. He already had that planned."
