Who doesn’t want to see a celebrity fall on his/her arse? Or fly through the air for that matter? How about when the celebrity is super nice and you feel kind of bad for them and they still fall on his/her arse and flies through the air? That will probably be the case tonight on the new Celebrity Circus, on NBC. Watch Rachel Hunter, Christopher Knight and Antonio Sabato Jr. Duke it out on the trapeze, on Fancast.
