Christina Aguilera visited Haiti earlier this week to spend time with families displaced by the 7.0 magnitude quake, serve meals at a school and even sing for some Port-au-Prince children.

“I was so moved by the devastation in Haiti but also by the spirit of its people,” the singer, 29, who traveled to the country with husband Jordan Bratman, said in a statement Thursday. “[The children] have such joy and are eager to learn despite the destruction around them.”

Aguilera, an Ambassador Against Hunger for the World Food Programme, toured the country with WFP aid workers and served rice and beans to children at two schools in the Haitian capital.

“The children deserve a chance and I want to make sure they get a chance,” says Aguilera, who also met with mothers and children who have been living in refugee camps since the January earthquake.

The Grammy Award-winning star also sang “Happy Birthday Haiti” to a class in Port-au-Prince, highlighting how reconstruction efforts have given the country a new start.

“I urge everyone to go to www.wfp.org/christina and donate so we can bring food to these mothers and children and help them rebuild their lives,” says Aguilera.
