NEW YORK — Christina Aguilera says that although she went to Rwanda to help others, she ended up helping herself.

The 32-year-old singer visited Rwanda in June for a hunger relief effort. She said the experience helped her ground herself.

“It came at a time in my life when I really needed to be far removed from anything to do with work or being on camera,” the Grammy winner said in a recent interview. “It came at a time in my life when I needed to sort of experience what’s going on with the world beyond entertainment.”

Aguilera has been a spokesperson for Yum! Brands’ World Hunger Relief effort since 2009. She said being a mother made her feel more empathetic for those suffering from hunger around the world.

“It’s so sad to think there’s nothing that sets any of us apart,” she said. “And when you go into the field, you really see that and feel that we’re all one in the same, it’s just we’re born under different circumstances, and it’s sad and I don’t understand why, but I feel what I feel and I did what I can.”

On her Rwanda trip, “The Voice” mentor served food to children and visited refugee camps, which she called “one of the most difficult moments.” Her PSA debuts Thursday and features her song “Light up the Sky.”
