Jon Hamm, Mishca Barton, LeAnn Rimes & More Enjoy Hollywood Domino Night [PHOTOS]

An eclectic mix of celebrities attended the 5th Annual Hollywood Domino Gala at the Sunset Tower Hotel last night (February 23) in West Hollywood, California.

Mad Men’s Jon Hamm really seemed to be enjoying himself, as did Edward Norton. While LeAnn Rimes (wearing a dangerously low-cut dress), Mischa Barton and AnnaLynne McCord looked to be enjoying the attention they were getting at the party.

The evening was a benefit for Artists for Peace and Justice which was founded by Crash director Paul Haggis. The organization encourages peace and social justice and addresses issues of poverty and enfranchisement in communities around the world.

The organization’s immediate goal is to build schools to serve the poorest areas of Haiti, providing an education, hot meals, clean drinking water and regular medical treatments to the children living in the slums.
