Rebel Wilson in Vic for defamation case

Hollywood film star Rebel Wilson says the truth must come out during an upcoming defamation trial in Melbourne against the publishers of Woman's Day magazine.

Speaking outside the Supreme Court of Victoria on Friday, Wilson said she was unable to give her "side of the story" before the trial, which is due to begin on Monday.

Wilson is suing Bauer Media for defamation over a series of magazine articles she says cost her movie roles by portraying her as a serial liar.

The Bridesmaids and Pitch Perfect actor, and former Sydney and Melbourne resident has flown in from the United States for the trial and plans to spend the weekend catching up with "all my favourite restaurants".

"Unfortunately the judge said I can't say anything until I start giving my evidence on Monday," she said.

"I just think that's really important, that the truth comes out."

She was present in court on Friday during a hearing where lawyers discussed a range of pre-trial issues.

Wilson alleges Bauer Media damaged her reputation by printing articles that claimed she used a fake name, and had lied about her age and background.

The articles appeared in several of the group's magazines, including Woman's Day and Australian Women's Weekly.

According to court documents, she claims a Woman's Day article from May 2015, with the headline "Just who is the REAL Rebel?", imputed she was a "serial liar who has invented fantastic stories in order to make it in Hollywood".

On Friday, she said she had not been able to audition for movies because of her pending trial.

However, she planned to make the most of Melbourne while in the city.

"I used to live in Melbourne, it's really good to be here, so I'm going to have a great weekend," she said.

"It's my grandpa's 90th birthday as well this coming weekend so I'm kind of doing double duty."
