Simpson took a regular job and pretended she wasn't herself when people recognized her. It was part of an April Fool's Day special she taped for CBS, called "I Get That A Lot."
LeAnn Rimes did the same thing, except she took food orders at a diner in Nashville. Heidi Klum worked at a pizza shop, "Survivor" host Jeff Probst was a cashier at a pizza shop and Mario Lopez sold hot dogs from a sidewalk stand in New York City.
"I Get That A Lot" airs April 1.
