The crowd inside the Ryman Auditorium Monday night (Jan. 14) erupted when Sharna Burgess joined her Dancing With the Stars partner Bobby Bones onstage.

She was an unannounced guest at the charitable Million Dollar show, and it was a treat:

The Million Dollar Show is an annual fundraiser for St. Jude Children's Hospital, and the 2019 variety show included performances by Luke Bryan, Lady Antebellum, Cole Swindell and a number of surprise guests like Burgess.

Bones, a popular radio personality, won Season 27 of Dancing With the Stars with Burgess in what most called a surprise victory.

"Sharna, our first day ever dancing, she said, 'OK we've got a lot of work to do,'" Bones told the crowd. "It's that look whenever you get an order of food that is not right, and you're like, this isn't right. That's what she looked like when she saw me."

"Every time that we danced, if you watch back on YouTube, Sharna smiled the whole time, but the bigger her smile was, the more she was telling me exactly what to do through her teeth," he joked.

Bones set up Burgess' surprise entrance by bringing out the DWTS mirrorball trophy and doing a few dance steps before saying, "This doesn't feel right." The crowd picked up on the hint immediately, and Burgess strolled in stage right to one of the loudest applauses of the night.

Besides putting in some work on the microphone, the duo enamored the crowd with two dances from DWTS including a favorite: the MC Hammer dance.

Bones still doesn't consider himself a great dancer, but he has proven to be pretty good at fundraising. During the show, it was stated that Bones' efforts have so far raised more than $10 million for St. Jude’s Children's Research Hospital.
