Supermodel Heidi Klum attended Cirque du Soleil's Zarkana on Friday, July 20 at Radio City Music Hall. Following the performance, Klum visited with cast members backstage.

Zarkana is an acrobatic spectacle that blends circus arts with the surreal to create a world where physical virtuosity rubs shoulders with the bizarre. The diverse cast features more than 75 international artists. The production will move to Las Vegas' ARIA in November.
