Their assignment was to makeover the home of a family who just happens to love "Dancing."
"I was watching it one day and I just thought, 'I wanna be part of something like that,'" said Hough. "I wanted to get in there and actually help build a house."
"When we went it was just such a blessing and an honor to be there to help people," said Ballas. "We tore that house down with our bare hands."
"It was amazing experience," said Hightower. "It's so nice to be able to give back to others as well. I'll be watching to see how they love their new home."
"When the celebs come on, in a matter of hours where you see the change take place," said decorator Michael Maloney. "It takes over and it's magic."
"Get some tissues," said Dovolani. "It's emotional, you'll enjoy us create a dance and do some construction. It's gonna be a very heartfelt story."
Watch the stars of "Dancing With the Stars" and "Extreme Makeover: Home Edition" join forces to make a difference Sunday night at 8 p.m. on ABC7.
