Labor MP Emma Husar is gearing up for a defamation lawsuit against the media outlet that revealed bullying and sexual harrassment allegations against her.
The Western Sydney MP is also considering taking her own party to court, as she fights to hold onto her seat.
Ms Husar told parliament on Thursday she had launched legal action against BuzzFeed and journalist Alice Workman over an August 2 story.
BuzzFeed published the allegations made against Ms Husar in a confidential Labor internal investigation, which included evidence from more than 20 people.
The piece included allegations she flashed another federal MP in his office, which she and the other MP denied.
The investigation found she had mistreated her electorate staff, but it did not find evidence to support the flashing claims or allegations of sexual harassment.
"They went ahead and published their slut-shaming story knowing with full intent that it would go viral," Ms Husar told parliament.
"I am not a bully. I am not Sharon Stone. I am not a thief. And I did not deliberately misuse my work expenses."
BuzzFeed said it is aware the proceedings had been issued.
"We're considering our position with our lawyers and will respond in due course," BuzzFeed said in a statement to AAP.
Ms Husar announced in August she would not contest the next election, as she faced the internal investigation.
But the member for the NSW seat of Lindsay has since changed her mind and rejected suggestions she is no longer the Labor candidate for next year's federal poll.
NSW Labor officials will meet on Friday to settle on a preselection process to replace Ms Husar.
But she has told The Australian she will fight the process through the courts if necessary.
