(Get a dance-by-dance recap of all the action in week 10 of 'Dancing With The Stars.')
It's a big two-hour show on Tuesday night. Ricki Lake, Rob Kardashian and J.R. Martinez will be performing their favorite dances of the season.
Then the two couples who get the most votes will perform an Instant Samba for the judges before one of them is crowned the champion.
Everyone from season 13 will be here to cheer on their cast mates, and there will be an opening number with all the castmembers.
And in the race for the mirror ball trophy, it really is too close to call.
Rob Kardashian and Cheryl Burke emerged as the new leaders after the judge's voting on Monday night. They earned triple 9s for their elegant Waltz, and then impressed the crowd with their freestyle routine. The judges gave them a perfect 30 for that dance - their first of the season. On Tuesday night, they'll dance the Fox Trot.
"I'm so relaxed right now. I mean, literally, last week, we got our first 10 ? we won the Cha Cha relay. It was the perfect transition into this week. We're peaking at the right time," Kardashian said.
Ricki Lake and Martinez tied for second with 54 out of 60.
Lake has been nothing if not consistent this season, and she played that out Monday night as well. She was awarded nine out of 10 from all three judges on both of her dances. Tuesday night, she'll perform the Tango.
Martinez stumbled a bit with his Cha Cha, and earned 24 points from the judges. But he did not let that get him down, and he returned for a high flying Freestyle. He and Karina Smirnoff were given a perfect 30 for that routine, and on Tuesday night, they will dance the Jive.
"Cha Cha is one of the easiest dances. That's the funny part. He is so much better at more complicated dances because then, I think, you just, you dive into it," Smirnoff said.
Who will win season 13 of "Dancing With The Stars?" In our exclusive poll done by SurveyUSA, 52 percent of those surveyed said it should be Martinez, 28 percent said Kardashian and 19 percent said Lake.
