'Dancing's' Most Impossible Week?

By

Having to perform three dances in one night had some of the Dancing with the Stars contestants calling this their "most impossible week ever." After they caught their breath, ET caught up with the remaining stars backstage to get their reactions on the night.

"It doesn't seem real," said an elated Ricki Lake when asked about her perfect scores.

Ricki and her pro partner Derek Hough became the second Season 13 couple to be awarded three 10s for one of their performances.

J.R. Martinez was left in disbelief as well, but for the wrong reasons.

"Obviously this week, physically, you start to get exhausted," said J.R. Martinez, who landed close to the bottom of the scoreboard. "And then hurting the ankle definitely didn't help."

"We're just hoping and praying that the momentum of the season and the confidence of the people at home will push us through into the finals," said J.R.'s partner Karina Smirnoff. "And once we're there, we are going to come back and deliver like we used to -- unlike tonight."

"I have a lot of confidence going into next week," said Rob Kardashian, who landed in second.
