NKOTBSB to perform on 'Dancing'

LOS ANGELES, April 22 (UPI) -- Pop groups NKOTBSB and Hanson, along with "American Idol" castoff Pia Toscano, have been booked to perform on "Dancing with the Stars," ABC said.

Hanson will perform their new song, "Give a Little," during the 1-hour special "Dancing with the Stars: The Road to the Finals" Tuesday, the network said Friday.

"Within the live hour, the remaining couples will look ahead, through live interviews and video, to what it will take for each of them to reach the finals. Past 'DWTS' celebrities and the judges will also provide their commentary on each couple," ABC said in a news release.

Also performing in the "Road to the Finals" special is the cast of the Broadway musical "Rock of Ages," starring Constantine Maroulis and Rebecca Faulkenberry.

On Wednesday's "Dancing with the Stars the Results Show," another couple will be eliminated from the competition and pop icons NKOTBSB [otherwise known as New Kids On the Block/Back Street Boys] will perform their hit, "Don't Turn Out the Lights," as well as a mash-up of their songs "Step by Step" and "I Want It That Way."

Toscano is to sing "I'll Stand By You," accompanied by professional dancers Mark Ballas and Karina Smirnoff.

Toscana and Ballas are rumored to be dating.
