Gwen Stefani: L.A.M.B. Fashion Week Show!

Gwen Stefani walks the runway with her adorable son Kingston at her L.A.M.B. Spring 2011 fashion show during NY Fashion Week at Lincoln Center’s The Theater on Thursday (September 16).

“It’s all about what I want to wear really,” the 40-year-old fashion designer said about her new collection. WWD says that “the lineup was pure Gwen and retail-ready, if not necessarily revolutionary.”

Backstage, Kingston wanted to dance, so one the show’s assistants danced with him. Ha, so cute!

After the show, Gwen took a dress right off the runway and wore it to the after-party!
