'Dancing''s Mark Ballas: Chelsea Kane Was First Not to Cry in Rehearsal

"Dancing with the Stars" pro Mark Ballas says his partner Chelsea Kane has reacted well to the pressure of the competition and surprised him by not shedding any tears during their grueling rehearsals.

ET was with the pair -- now among the top five couples on the show -- as they rehearsed for their performances involving the waltz and the salsa. Mark reveals that they got the waltz done in a record two days last week and then shifted their attention to performing a sexy salsa routine.

Chelsea said it really hasn't sunk in that she made it to the top five, but she credits her loyal fan base with giving her a big boost. "To stay in the competition so long and have new fans, and making the old fans proud, it's been such an awesome experience, and I'm so happy to still be here."

Despite the fierce competition among contestants, Chelsea said there's a lot of support and cheering going on backstage. "We see each other all day in the studio. And being that we're trying to take each other down - literally and physically -- just like, knock out the competition, we all have each others' backs. It's a really cool support system backstage after everyone performs."
