OK! Exclusive: 'Dancing With The Stars' Contestants Get Silly During Rehearsals

With six couples left, the couples of Dancing With The Stars will be thrown into some things that haven't yet this season. The very first group dance of the season will show off the star's best Cha-Cha-Cha. The gang shared the stage last night with music from New Kids on the Block and Backstreet Boys and American Idol cast-off, Pia Toscano.

Last night we said goodbye to Chris Jericho and his partner, Cheryl Burke who landed at the bottom of the leader board on Wednesday night after his Tango failed to wow the judges.

Next week, Chelsea Kane and her partner Mark Ballas will take on the Paso-Doble for the first time this season while Hines Ward and his partner Kym Johnson will try to take over with their Tango.

Chelsea and Mark are currently sitting at the top of the leader board tied for first with Romeo and his partner, Chelsie Hightower. Who do you think will claim the top spot this week?
