Chelsea Kane Lights a Competitive Fire for 'Dancing with the Stars'

Chelsea Kane has gone from unassuming Disney star to competitive powerhouse during this season of "Dancing with the Stars" as she revealed in an interview during her rehearsal for this week's paso doble.

"Now that you can kind of see the light at the end of the tunnel, I want to go all the way," said Chelsea. "So hopefully we do."

Chelsea revealed the sacrifices she's had to make for the sake of the mirror ball trophy, saying, "My social life has definitely taken a backseat to the show... We did the math the other day that we've been rehearsing for, like, over 50 straight days. So you're starting to get to that point where your body's a little tired."

That wear and tear showed during Chelsea and Mark Ballas' first team rehearsal with last week.

"Tuesday night we were all pretty exhausted from the live show and I literally spent most of [the rehearsal] just trying to stop everybody from fighting," said Chelsea, who was named troupe leader. "We have a great team and an awesome song, so I'm excited."

Chelsie Hightower, Romeo, Ralph Macchio and Karina Smirnoff make up Chelsea and Mark's squad, which will dance to a song by Lady Gaga.
