'I saw it out to the bitter end, ' she said.
Wilson's lawyers on Friday sought leave to appeal against the reduction in the High Court - Australia's highest judicial body - but the application was refused.
Rebel Wilson said she was glad she'd stood up to "a bully" despite losing her bid Friday to keep most of the record payout awarded to her in her defamation case against an Australian magazine.
Wilson's barristers, Matthew Collins QC and Renee Enbom, appeared before the High Court in Canberra on Friday seeking special leave to appeal after she was forced to repay nearly 90 per cent of her record A$4.7 million payout to the Woman's Day publisher that defamed her.
But in June this year the Court of Appeal forced Wilson to pay back $4.1 million of those damages and 80 per cent of the magazine publisher's legal costs, finding "there was no basis in the evidence for making any award of damages for economic loss".More news: Arjun Kapoor & Malaika Arora to tie the knot?
She added: 'The damages that I did receive are still so significant, so close to the Australian record, and I'm so proud of myself for seeing it through.
The Supreme Court of Victoria heard those articles alleged that she had lied about her name, age and upbringing.
Wilson initially sought $7 million in compensation over the eight articles, which she earlier described in court as a "malicious, deliberate take-down" of her.
"What the court of appeal did was not confine itself to the facts found by the trial judge", he told the High Court.
"In our opinion there are insufficient prospects that an appeal will succeed", Justice Virginia Bell said at the court in the national capital, Canberra.More news: Stan Lee proclaims love for his fans in touching final video
Wilson said the whole reason for bringing her case is that she "really wanted to stand up to a bully".
"But the great thing about today is that it brings it to a definitive end".
"To me it was never about the money".
At the time, Justice Dixon said Bauer Media failed to properly investigate the claims made against Ms Wilson and then published them despite knowing they were false. And I've done that so successfully.More news: Ireland restore Devin Toner to side for All Blacks Test in Dublin
