Kristen Bell urges you and her "Gossip Girl" castmates to join her in preventing children soldiers in Uganda.

Kristen Bell, whom everybody loves from her time on "Veronica Mars" and in her current gig as Gossip Girl herself, has taken to the Internet to promote her favorite charity. Invisible Children works to save children in Uganda from being abducted into the army and forced to fight as soldiers.

Later this month, there's a big event sponsored by the charity taking place in dozens of cities around the country. So Kristen has posted a video of herself on YouTube urging her fellow "Gossip Girl" castmates to join her in the fight. You can see the video -- in which she pokes a bit of fun at both the sexy ensemble and the fans who love them -- here. While there, perhaps you'll become interested in "abducting yourself" and aiding this very noble cause.

So, do you think Ed Westwick will show? If so, sign us up.
