Gwen Stefani spent her Saturday afternoon with fellow famous moms and lots of kids at the LA launch of her Harajuku Mini line for Target. The party, which featured face painting, an ice cream bar, and a coloring wall, was a big hit with the tots in attendance, including Gwen's sons Kingston Rossdale and Zuma Rossdale. The celebration was capped off by a supercute kids fashion show full of the clothes Gwen designed for the retailer, and she took her final bow with her children. We had a chance to chat with the multitalented mom during her big day. She told us how her boys inspired her creations and talked about No Doubt's upcoming album before posing for pictures with Maya Rudolph, Selma Blair, Paula Patton, Michelle Monaghan, Ali Larter, and more of her friends inside the soiree. Gwen said the clothes from the debut Harajuku Mini line are essentially kid versions of what she likes to wear, and the next day, she was spotted shopping at Target for some of the pieces from the collection with Kingston and Zuma! It was an overall busy weekend for the singer, who also took time out to attend Saturday night's MOCA gala with Kirsten Dunst, Rachel Zoe, and other stylish celebrities.
