Gwen Stefani: Superhero Party with Kingston & Zuma!

Gwen Stefani holds on to her little superheroes, Kingston and Zuma, as the three go to a fun party on Saturday in Sherman Oaks, Calif.

The 40-year-old rocker played on a slide with Kingston, who dressed as Batman but had his face painted like a tiger, while Zuma played with a giant parachute.

Also making an appearance at the party was a costumed Wolverine!

FYI: Gwen is wearing an AllSaints Tower Dress!
