Celebrity Circus

What do you get when you take a supermodel, a singer, an olympic athlete, some actors and toss them all under the big top?  You get "Celebrity Circus," a whole new kind of reality show debuting Wednesday on NBC.

Welcome to the greatest show on earth.

The greatest reality show, that is.

This summer, NBC invites viewers inside the big top for a celebrity competition that requires strength, grace and precision.

"Celebrity Circus" puts six famous stars in the center ring, as they compete before a live audience in the ultimate showdown of circus talents.

Supermodel Rachel Hunter says "what we're doing in 8 weeks is what most performers take 8 years to figure out how to do."

Supermodel Rachel Hunter is joined by "Jackass" star Jason "Wee Man" Acuna, Olympic gold medalist Janet Evans, actor Antonio Sabato Junior, singer Blu Cantrell and former "Brady Bunch" star Christopher Knight.

Christopher Knight says "you're seeing us in the first week, literally like the bad news bears of circus."

It's grueling stuff, even for an olympian.

Janet Evans, a 5-time Olympic medalist, says "eight weeks, five days a week, eight hours a day harder than I trained for the Olympics."

Rachel Hunter says "some people think lions and tigers and all that, but it's not really like that; it's pushing our physical abilities to the absolute limit"

When asked what he wants the audience to get out of it, Jason "Wee Man" Acuna says "I want them to laugh till they die and have the best time.  I want them to feel like - like they're there."

Just don't expect them to put Barnum and Bailey out of business.

The celebs get critiqued every week by an expert panel of judges then, at the end, America gets to decide who wins celebrity circus.
