Ian Somerhalder & Nina Dobrev: 'Ripple Effect' Benefit!

Ian Somerhalder and Nina Dobrev step out in style for “The Ripple Effect” at the Sunset Luxe Hotel on Saturday (December 10) in Los Angeles.

The event benefited The Water Project, which provides clean drinking water and sanitation solutions to African villages in need.

Ian also celebrated his 33rd birthday late last week! “Happy Birthday to my favorite Vampire @iansomerhalder . It’s 1111, and your birthday, Make A Wish,” Nina wrote on her Twitter account. Aww!

Also pictured inside and attending: Emmy Rossum and Krysten Ritter (in Philosophy di Alberta Ferretti).

FYI: Nina is wearing Monique Lhuillier paired with Brian Atwood shoes. She and Krysten also rocked Neil Lane jewelry. Emmy also wore Brian Atwood shoes and a Naven dress!
