On Sunday, Kristen Bell will turn 30-years-old and is using her big day to help make a big difference.

The star has teamed up with Charity: Water to raise money for their important work bringing clean drinking water to impoverished nations.

On a special donation page, Kristen writes:

“A billion people in the world are living without clean water. EFF THAT. Water-borne illness
is the second highest cause of childhood death in the world. NOT ON MY WATCH. 45,000 people will die this week alone from contaminated water illnesses. Y’ALL, LETS GET OFF OUR HINEYS AND FIX THIS. Please help me get to my goal of 100K and let’s have a clean water toast.”

So far, the star has raised almost $6,000 and hopes to collect $100,000 by Sunday! That’s a lot of moola!
