Nicole Richie and Joel Madden took a break from house hunting to show their charitable sides at the Sephora Project Launch Party in LA last night. These two are no strangers to giving back, and they spent their night chatting with teenagers from Girls For a Change, which encourages girls to make a difference in their neighborhoods. As the happy couple continues to balance work, family, and doing good, it's no wonder they need to find an intern to help them with their own foundation.
