All-American cutie!

Wearing a patriotic Captain America costume, Gwen Stefani's son Zuma got pampered Friday with a trip to a nail salon in Studio City, Calif. Complementing his superhero costume, the tot -- who turned 3 on Sunday -- opted for red and blue nail polish.

When Zuma decides to change out of his costume, he'll certainly have plenty of stylish outfits to choose from: his mom, 41, is currently designing a line of adorable kids clothes for Target. The collection, called Harajuku Mini, hits stores in November 2011 and January 2012.
