Dancing Pros Invade Extreme Makeover: Home Edition

As this season of Extreme Makeover continues, I'm impressed by all the guest stars and celebs they are bringing on the show.

This week, it's Dancing With the Stars.

Dancing pros, Derek Hough, Mark Ballas, Tony Dovolani, Anna Trebunskaya and Chelsie Hightower all helped out this week. The gang was there to help rebuild the home where Rhex Arboleda, an unsung hometown hero, lives with his wife and five children.

Rhex started a program called Move to the Groove that encourages kids to get up and move, dance and be active," says DWTS pro Derek Hough.

"This family of seven was living in a 500-square-foot home, but they were the most positive people," Hough says. "It was wonderful to be part of that energy, to give back to someone who had given so much but had so little."

Throughout the weeklong build with Ty Pennington and his crew, Hough insisted he be allowed to "get [his] hands dirty."

"After a few hours of swinging a hammer I was quite sore, I have to admit," Hough says, laughing.
