Rebel Wilson became emotional and broke down in tears in court on Tuesday as she testified that a series of magazine articles published in Australia hurt her career.
She stated the articles were a deliberate attack on her character.
"These articles were a deliberate malicious take-down of me," the actress testified.
Wilson is suing Australian publisher Bauer Media for defamation over several articles published in 2015 that the Australian-born actress said led to her film contracts being terminated. The articles said Wilson had lied about her name, age and upbringing in Australia.
Wilson wiped away tears as she testified in the Supreme Court of Victoria, rejecting the publisher's argument that the stories were light-hearted and had no serious impact on her career.
Wilson, known for her work in comedies such as "Pitch Perfect" and "Bridesmaids," said she has only had two roles since the articles were published, one for the film "Absolutely Fabulous" and the other a stage role in London.
"It's not lucrative," she told the court. "The reason why I'm here today is to stand up for myself and to stand up for my family, who've been harassed."
Wilson is seeking unspecified damages from the publisher.
