Country music couple Garth Brooks and Trisha Yearwood have returned to Haiti to launch a new housebuilding project to help those still homeless after a 2010 earthquake ravaged the nation.

Brooks and Yearwood were among the celebrities who headed for Haiti to help the Habitat for Humanity campaign in the months following the quake, and now they're back in the Caribbean with former U.S. leader Jimmy Carter.

With the stars' help, Habitat For Humanity officials are hoping to build 100 new homes in Leogane, a town hit hard hit by the earthquake, which destroyed more than 100,000 homes.

The new housebuilding push is part of the 29th annual Jimmy and Rosalynn Carter Work Project.
