Clueless star Stacey Dash is nursing three cracked ribs when a circus stunt on a new reality TV show went wrong.

The actress fell while trying to climb a length of fabric, in a stunt for the forthcoming Celebrity Circus. Dash isn't the only injured participant; former Brady Bunch star Christopher Knight fractured his forearm on a giant disc dubbed the German Wheel; and Olympic swimmer Janet Evans fell from a trapeze.

The show, which also stars model Rachel Hunter and Jackass' Wee Man, premieres on NBC on Wednesday.
