"Every night, millions of children go to bed hungry, and every night millions of parents can't find the words to make it all okay," Aguilera says in the 30-second PSA for Yum! Brands' annual World Hunger Relief effort. "But you can. Give them a voice at FromHungerToHope.com."

Aguilera backed up her words with actions when she met with mothers in Guatemala and Haiti while volunteering on her hunger relief trips.

"It's been amazing to be a part of Yum! Brands' World Hunger Relief, raising $115 million and providing 460 million meals for hungry women and children," said the Grammy winner, whose new album, Lotus, releases November 13. "I mean, who could ask for more than that?"
