According to the lawsuit filed Friday in Los Angeles Superior Court, Richards and Anderson were at the River Rock Casino Resort in British Columbia, Canada, on Nov. 9, 2006, to work on the upcoming film "Blonde and Blonder."
When Richards saw Scott Cosman and Rik Fedyck taking her picture, according to the lawsuit, she became enraged, called them "paparazzi scum" and other names, assaulted them, seized their laptop computers and threw the laptops over a hotel balcony.
The confrontation, which lasted more than 20 minutes, was recorded by hotel security cameras, according to the photographers.
Afterward, they said, Richards and Anderson "made repeated false and defamatory statements to law enforcement and various media outlets which were deliberately calculated to embarrass, humiliate and ridicule plaintiffs."
Attorneys and representatives for Richards and Anderson did not immediately respond Saturday to e-mails and phone calls seeking comment.
The photographers, who seek unspecified damages, said the incident caused them to lose revenue when clients abandoned them and also caused them emotional stress.
NEW YORK - Pop legend Elton John will celebrate his 60th birthday with a record-extending 60th performance at Madison Square Garden on Sunday.
"There are very few artists that could even think of setting a record like this, let alone achieve it," said Jay Marciano, president of MSG Entertainment.
The concert will be recorded and broadcast April 5 as a two-hour special on MyNetworkTV, a mini-network on Fox stations.
John has owned the record for most performances at the Garden since October 2001. Previously, the Grateful Dead held the record, playing there 52 times.
The singer recently announced he would make his back catalog of more than 30 albums released over 40 years available for digital download, a move that also coincided with his birthday, as well as the release of a new compilation album, "Rocket Man." The newly digitized albums include John's 1969 debut, "Empty Sky," and perennial favorites such as "Goodbye Yellow Brick Road" and "Captain Fantastic and the Brown Dirt Cowboy." The tracks, more than 400 in all, will be available for download starting Monday.
