The Vampire Diaries cast has a long list of charities they tirelessly promote, and Kat Graham (Bonnie) spent some time this summer raising money for The Water Project, an organization that brings clean drinking water to those in need. Donations help fund the building of wells in areas of the world where safe drinking water is scarce.

On December 10, Kat will continue her fundraising efforts with co-star Ian Somerhalder (Damon). She will host and he will chair the red carpet event, which will also feature a multi-course dinner and both silent and live auctions. Ian’s organization, the Ian Somerhalder Foundation, is also taking part in “The Ripple Effect.”

Tickets cost $250 and are going quickly. If you’ll be in the Los Angeles area, help Kat and Ian with this important cause by purchasing tickets here.
