No doubt, first lady Michelle Obama had a fun and lucrative Sunday at the Beverly Hills home of singer Gwen Stefani.

Obama, on a West Coast fundraising swing for her husband's re-election campaign, mingled with supporters and delivered a keynote address at a $2,500-per-family event on the lawn beside Stefani's outdoor pool. It was billed as a "Sunday of Fun" on invitations to donors.

Organizers provided fake tattoos on the tennis court for kids, while platters of roasted meats and cookies sat on tables by the hot tub for parents, according to press pool reporters on scene.

Bandmates from No Doubt sat in the crowd, many with children on their laps. Stefani's children - Kingston, 6, and Zuma, 3, - were also there. Her husband, singer Gavin Rossdale, was said to be on tour in Europe, a campaign official said.

Given her audience, Obama delivered a kid-focused pitch for her husband's campaign.

"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," she said.

"I am not just talking to the adults here today. I am talking to the young people here as well. All of our young people - you might not be old enough to vote. You vote at school, I know - I met several young people who are going to be voting for my husband, who are 10 and under - we accept those votes," she said. "But you can play an important role in this election, too. I want you all to feel empowered."
