Punk rock princess-turned-designer Gwen Stefani wrapped up New York Fashion Week with a rocking runway show last night for her L.A.M.B. Spring 2011 collection. Before the show started, sons Kingston and Zuma, husband Gavin Rossdale and No Doubt bandmates Tony Kanal and Tom Duman hung out backstage with Stefani. Front row celebrities included Debbie Harry, Mel B (wearing a black L.A.M.B. catsuit), rap mogul Russell Simmons and fellow designer Christian Siriano. "I feel like a lot of people, me included, have been wearing a lot of black, white and gray, so we decided to go really colorful. [This collection] is kind of this dance-all African queen," she told us. It's fun to have all those prints and I think prints are definitely hard to do and do them good, but we really pulled it off with this collection." We loved the eclectic mix of maxi skirts, harem pants, T-shirts and crop tops, all styled in Stefani's signature style. But the moment that really stole the show? When a leather jacket-clad Kingston hopped up on stage during the finale to congratulate his mom.
