"I'm doing a number with [Gleb Savchenko]," Sharna explained. "It's a solo piece. It's going to be really beautiful, and will hopefully connect with a lot of people."
Sharna described the story of the dance as a "very broken, tormented love story. That love that you can't walk away from, but you should." She added that she's really "excited" about the dance. "I love playing things like this. Not very often do we get to do things like this, just show pieces."
Plus, she loved dancing with Gleb, who she'd never danced with before. "Gleb is a fantastic dancer!" she gushed. "It just feels amazing to dance with him, so I'm all around super excited."
And we're excited to see it!
