Celebrity Liar (2010)

The premise is simple: two celebrities tell the same story as if it happened to them. The LIVE web audience then gets to choose which star they believe is lying. If the audience correctly chooses the liar, the star who was telling the truth gets a point. If the audience votes the other way, the liar gets two points. Viewers can participate live via the chat room, which is moderated by the lovely co-host, Louise Roe (from "Plain Jane" on the CW).
