Fawcett, a well-known celebrity photographer in Sydney, is suing The Sun-Herald newspaper for defamation over an article that said he was Sydney's most disliked freelance photographer and was determined to "wreak havoc" on Kidman's private life.

A jury has already found that the article defamed Fawcett. The current hearing is to decide whether the newspaper's publisher, Fairfax Media, should pay the photographer damages, and how much.

Kidman described two other times that Fawcett had allegedly been intrusive when trying to photograph her — once while she was on her honeymoon with country music star Keith Urban in Tahiti in mid-2006, and once after Christmas in Sydney last year. She said he was one of the reasons she employed full-time security guards.

"I have been pursued many times," Kidman said. "I have had this happen in relation to this particular man ... so many times.

"I employ people to protect me now. I employ people 24 hours to protect myself because I don't feel equipped to handle things," she said.
