Gwen Stefani has a mini-model on her hands.

At the end of her L.A.M.B. fashion show in NYC Thursday, the 41-year-old designer walked the runway with her four-year-old son Kingston. See more Kingston shots.

This isn't the first time the fashionable tot has strutted his stuff on the catwalk; he made his runway debut at his mom's fashion show September 16.

Still, the day wasn't just about Kingston -- after all, the No Doubt rocker had a fashion show to produce.

"I was sitting in the showroom waiting for those clothes to get there. And I was like, 'Why am I sitting here? Where are the clothes?'" Stefani told USA Today. "And then they get there and then it's all a scramble. And it's just the same every season, and I still love doing it."
