Gwen Stefani welcomes Michelle Obama at family party

American star Gwen Stefani had welcomed a very special guest at her house yesterday. None other than America's First Lady Michelle Obama joined the singer at her home here for a family party which was also attended by Nicole Richie, her husband Joel Madden and actress Alyson Hannigan. Michelle, who is presently in Hollywood to raise funds for her husband's re-election campaign, also helped the host with face painting and balloon sculptures. The fund-raiser party was accessible to a four member family in just $2,500. Expressing her gratitude, Michelle said, "Barack can't do it alone. He's not Spider-Man. He's not a superhero. He's a human, so we need your help. I am not just talking to the adults here today. I am talking to the young people here as well. Stefani's bandmates were thrilled to meet the First Lady. An excited Adrian Young wrote on Twitter, "Life in (No Doubt) land gets more strange and wonderful everyday," while Tom Dumont called Obama "so warm and sincere".
