Jordan, aka Katie Price, has topped the most annoying celebrity Twitter user list, says a new poll.

According to the survey, headed by one-poll.com, 4,000 Twitter users voted the glamour girl, who has been using the social networking website to slam her estranged husband Peter Andre, who was placed second in the list.

'Jordan's Tweets are the worst. They are vile, unintelligible and bitter. She has nothing to say which appeals to anyone except herself,' the Sun quoted a spokesman for one-poll.com as saying.

Rapper 50 Cent, whose real name is Curtis James Jackson III, featured at the third spot in the worst Tweeters list.

Mariah Carey was voted the fourth worst Twitter user.

Sean P Diddy Combs rounded off the top five. Meanwhile, Stephen Fry was named as the most interesting celebrity Tweeter. Jimmy Carr, Phillip Schofield, Russell Brand and Barack Obama wrapped up the top five best Tweeters.
