Gwen Stefani performed her best version of "Wind It Up" on The Late Show With David Letterman, and like the incredible mom she is, she even brought along a special guest.

Awww. Little Kingston James McGregor Rossdale even got a cute Letterman t-shirt. It's nice to see that this pop star also seems like a great mom with her head in the right place. Yes. If you're reading this, Britney Spears, we are calling you out.
