Celebrity autobiographies are forgettable, if a hotel survey is anything to go by.
The five books most left behind are works by the rich and famous, the Travelodge survey found.
Most mislaid was Paris Hilton's Confessions of an Heiress, with Chelsea boss Jose Mourinho second with Made in Portugal.
Third was Jordan, or Katie Price, with A Whole New World, with Big Brother star Jade Goody fourth with Jade's World and Sir Alex Ferguson fifth with Managing My Life.
While JK Rowling's Harry Potter and the Philosopher's Stone was sixth, two more autobiographies were in seventh and eighth - Tony Adams' Tony Adams Addicted and Paul Gascoigne's Gazza -My Story.
Travelodge operations director Kyle Rowe said: "We have been very surprised by the findings. It's the first time ever the top five books have all been celebrity autobiographies."
