Actor Leonardo DiCaprio has said he fears "stalkerazzi" photographers could cause a celebrity death.
DiCaprio says the paparazzi make his life "miserable"
So-called stalkerazzis follow famous people in cars and DiCaprio is concerned a fatal accident may occur.
"I hate a lot of them... but I have to find a way to deal with it until there's a law," he said.
"I hope there is for my sake and the sake of many others because there may be an accident someday and we may lose somebody," he added.
"I wish they wouldn't follow me around and make my life miserable."
DiCaprio's publicist, Ken Sunshine, told BBC News that the situation was "totally out of control".
"The context of that (DiCaprio's) statement refers to the stalkarazzis, who tail celebrities endlessly and follow them in cars, often trying to cause accidents so that they can get a photo which will be worth more money," he said.
Timberlake's relationship with actress Cameron Diaz has attracted attention
"The situation with these stalkarazzis in Los Angeles is totally out of control, and we all fear there will be another Princess Diana accident," he added.
Mr Sunshine also represents pop star Justin Timberlake, who obtained a restraining order against a photographer who allegedly stalked him earlier this year.
A judge in Santa Monica, California, granted the order against photographer Artemus Earl Lister in July.
A law was introduced in California in 1999, making it illegal for photographers to go on to private property.
Arnold Schwarzenegger, Alec Baldwin and George Clooney are among the many celebrities who have clashed with the "stalkerazzi" in the past.
Schwarzenegger, now governor of California, said he was once forced off the road when the car he was driving, carrying his two children, was chased by photographers.
Many photographers say they are just doing their job.
The Kingly Club in London's Soho recently began employing doubles to act as decoys, which it hopes will knock certain photographers off the scent of visiting celebrities.
A spokesman said the idea came after Hollywood actor Tom Cruise was provided with a decoy when he visited the venue.
