Jessica Simpson, LeAnn Rimes Fool Fans

The saying goes that everyone has a twin out in the world somewhere. Jessica Simpson and LeAnn Rimes will try to convince people of that when they take part in the CBS special, 'I Get That A Lot,' appropriately set to air on April Fool's Day.

The first of April is, of course, a day when people go out of their way to play jokes on friends and co-workers, and CBS is taking that idea to a higher level. The premise of the special is to take real celebrities, put them in jobs that are far from the stage and screen, and then have them convince the people who see them that they are not who they appear to be.

Cameras followed Rimes as she worked as a waitress in a Nashville diner. Simpson had a much harder job, that of an electronics specialist in a computer repair shop. When customers come in and declare each of them looks a lot like LeAnn Rimes and Jessica Simpson, respectively, they both declare, "You know, I get that a lot."

CBS has tapped several other celebrities to round out the hour-long special. Heidi Klum uses her supermodel abilities while working in a pizzeria, and 'Extra' host Mario Lopez finds a new trade while selling hot dogs. 'Survivor' host Jeff Probst counts his change as a grocery store check-out person, and actor/rapper Ice-T plays a shoe salesman. To find out if these celebrities fool the unsuspecting public, tune in to the CBS special on April 1 at 9 PM ET.
