Michelle Obama the guest of honour at Gwen Stefani's fundraiser
America's First Lady attended the soiree, called 'Sunday of Fun', at the No Doubt singer's Los Angeles home, with the event aimed at enticing politically-active parents to bring their children along with them for some games and food.
Tickets cost upwards of $2,500 per family of four and other guests included Nicole Richie, Joel Madden and Alyson Hannigan although Gwen's husband Gavin Rossdale was a notable absentee.
The 'Sunday of Fun' event was part of Michelle's husband Barack Obama's re-election campaign and Michelle thanked Gwen, who has two sons, Kingston, six, and three-year-old Zuma, for hosting such a great bash.
She said: "I want to thank Gwen, in particular, for being so kind and gracious and hosting us all here at her beautiful home. And even though Gavin couldn't be here, I also want to say a special thank you to him as well, and also to Kingston and Zuma. I mean, they are letting all of us just enter their house, all the chaos, and they're being so good about it today. So thank you, guys, for letting us come - indeed."
Barack will run against Mitt Romney in a bid to become the US President for a second term and Hollywood stars such as George Clooney and Sarah Jessica Parker have already hosted fundraising events for him.
