Christina Aguilera put her John Hancock on a 2010 Chrysler 300 Eco Style Edition car for charity — and raised $50,000!

The “Beautiful” songstress personalized the car, which was auctioned off by Stars for a Cause to benefit the United Nations World Food Programme, which is aiding relief efforts in Haiti.

Today, Stars For A Cause co-founders George and Laura Braunstein were able to present $50,000 to Kevin Sturtevant, Vice President for Development, Friends of the World Food Program, the U.S. Branch of the United Nations World Food Programme, for 100 percent of the proceeds from the SFAC charity auction of the Christina Aguilera-autographed Chrysler 300 Eco Style.

Aguilera was selected to personalize this one-of-a-kind, vanilla exterior and cactus interior luxury car. The eco-style edition uses recycled materials, such as recycled rubber for the floor mats, bamboo wood interior, 100 percent recycled metals, and includes a fuel efficiency system that reduces the eight-cylinder engine to four cylinders when necessary.

Launched in 2006, Stars For A Cause is a unique charity fundraiser that has helped raise money for various charities through the help of celebrities and the Hollywood community.
