Heidi Klum blew off some steam with a colorful troupe of circus performers at an afternoon performance of Zarkana by Cirque du Soleil at Radio City Music Hall in New York City, on Saturday afternoon, and it looks like the supermodel was having a ball!

Klum took her four kids to the popular show, and the VIPs were treated to full backstage access, where they got to clown around with the cast! The Project Runway host and her brood also got a chance to peek at some of the costumes and play with a few of the props.

Zarkana will perform at Radio City Music Hall until September 2nd, and will then head to the ARIA Resort & Casino in Las Vegas where it will take up residency in November.
