Christina Aguilera may be best known for her crazy curves, insane voice and tough judgment calls on The Voice, but the pop superstar also has quite the charitable side to her. In conjunction with Yum! Brand, the "Say Something" songstress helped raise over $37 million dollars to help fight world hunger last year.

The record-breaking money and food donation comes to Yum!'s World Food Programme and other hunger-relied efforts, including disaster relief and school meals programs.

"I'm inspired and proud of our employees, franchisees and their families who have raised record-breaking funds and food donations and volunteered in their local communities toward hunger relief," said David Novak, Chairman and CEO of Yum!. "With the help of our global spokesperson Christina Aguilera lending her voice, we were able to raise more awareness than ever about this critical issue."

According to the press release, since 2007, WFP has raised more than $185 million in cash and food donations to help combat world hunger. Every US dollar raised by the charity goes directly toward their efforts.

It's only fitting that Yum! would help to combat world hunger. The brand owns a slew of fast food restaurants, including KFC, Pizza Hut and Taco Bell.

When she's not helping to bring awareness to combatting world hunger, Aguilera is busy making music. Most recently, she teamed up with fellow pop diva Lady Gaga for a remix of Artpop single "Do What U Want."
