Taking a break from their busy professional lives, Kristen Bell and 90210’s AnnaLynne McCord got all philanthropical yesterday (June 23) as they attended the Invisible Children’s ‘How It Ends’ lobbying campaign rally in Washington, DC.

The young Hollywood starlets were among thousands of people from across the country who came together to lobby leaders to dismantle Joseph Kony Lord’s Resistance Army, a guerrilla group that is engaged in a 22-year violent campaign to establish theocratic government in Uganda.

The program included lobbying trainings, VIP speakers, a kick-off rally which culminated in an unprecedented outpouring of activism on Capitol Hill, with hundreds of meetings taking place between Members of Congress and their constituents.

Says AnnaLynne: “We’re lobbying and telling them what they need to do. It’s for us as a human race to come together to fight this sin on humanity, because that’s what it is.”

She adds that she’s determined to meet President Barack Obama – to discuss her advocacy work, of course. “I’d say, ‘Hello, Mr. President. My name is AnnaLynne McCord and I think there is a service to the greater good that has to be done and you need to do it with me!’ That’s probably how it would start, and then I’d shake a little and might even cry just from nerves. But then I’d be like, ‘You’ve got to hear what I have to say.”
