Nicole Scherzinger checks into hotels under the pseudonym Edna Krabapple.
The former Pussycat Dolls singer - who has been dating Formula 1 racing driver Lewis Hamilton for the past three years - uses 'The Simpsons' cartoon character's name in order to stop fans from discovering her whereabouts.
A source said: "Celebrities have been using fake names at hotels for years. Nicole's is tame compared to a lot of them but she loves 'The Simpsons' and thinks it's funny.
"It's done the trick so far as nobody has twigged."
Nicole's ruse was successful on a recent romantic trip to Paris with Lewis where fans showed up at a hotel where 'Nicole Scherzinger and Lewis Hamilton' were booked to stay, not realising that 'Edna Krabappel' was in another hotel.
Nicole is not the only celebrity to use a pseudonym.
British actress Kate Beckinsale has revealed she chose to call herself Sigourney Beaver on the "spur of the moment" because of her admiration for Sigourney Weaver, although her husband, director Len Wiseman, hates it when hotel employees call him "Mr. Beaver."
Ozzy Osbourne reportedly has two fake names, Harry B******s for when he books weekends away with his wife Sharon and the more sedate Prince Albert for other times.
