The pop princess topped the list because she consistently tops Google's most searched list and refuses to disappear from tabloid headlines, despite constantly complaining about appearing there.

Spears' high profile marriage to back-up dancer turned rapper Kevin Federline and constant mishaps with baby son Sean Preston also don't hurt her gossip value. Add to that the fact that she's about to pop out baby number two, and Spears won't be disappearing from the top of the list soon.

No surprise that Paris Hilton follows at number two. Since her sex tape was "accidentally" released, Hilton has been all over tabloids, the TV (she starred in four seasons of her reality show The Simple Life) and now on the radios. The first single from her CD Paris, "Stars Are Blind", was a surprise hit this summer and feuds with fellow socialites (think Nicole Richie and Lindsay Lohan) will keep Hilton in the public eye.

Angelina Jolie, Tom Cruise and Brad Pitt round out the top five. Other celebrities making an appearance on the most talked about list include Christina Aguilera, Mel Gibson, Justin Timberlake, David and Victoria Beckham, and Nicole Kidman.
