Paris Hilton has revealed she Google's herself instead of keeping a diary.

The socialite made the revelation in a court deposition in Miami, where she is being sued by the makers of her 2006 film Pledge This!.

The $8.3million lawsuit, filed by a former investor in the film, alleges that the movie suffered at the Box Office because Paris failed to promote it adequately.

However, lawyers for the actress claim she was asked to commit to last minute demands when her schedule was already full.

When asked if she kept a diary in her deposition, Paris replied: "I just press my name and Google it and see."

Paris also revealed that she was unsure about the frequency of her mobile phone usage because “I lose it all the time”.

“I've never seen a phone bill of mine in my life,” she added.

When asked about the role of a producer, she replied: "I'm not sure what a producer does, but - I don't know, help get cool people in the cast.”

Paris's attorney Michael Weinstein told the court yesterday that she was the “single busiest person on the planet”.

Pledge This!, which sees Paris star as the president of the exclusive Gamma Gamma Gamma Sorority at a fictional university, was panned by critics and only shown in 25 cinemas.

A trial is scheduled to begin in June.
