“Liar Liar” wasn’t just a movie for Jim Carrey — it’s also a way of life for the actor. At least that’s the claim of Brigid Sweetman, mother of Carrey’s deceased ex-girlfriend, Cathriona White.

Sweetman, who’s suing Carrey for wrongful death and challenged him to pony up an STD test, released a statement Tuesday, calling Carrey a “complete liar” for not producing the test results.

“One week ago, I offered to drop my case against Jim Carrey if he released his STD test from 2013 and it showed he was clean as he has told the world,” Sweetman said in a statement released by her attorney. “He has refused to release the test, which shows he is a complete liar and cannot be trusted to be honest with the public and the media in this case.”

Sweetman’s lawsuit alleges that Carrey contributed to White’s 2015 suicide by providing her with drugs and transmitting multiple STDs to her without telling her he was infected.

“Jim Carrey should be ashamed of what he did to my daughter. And he should be ashamed for how he has used his Hollywood attorneys to badmouth Cat’s husband Mark with the hope that nobody will hold him responsible for what he did,” Sweetman said in a statement after filing the lawsuit.

The complaint goes on to claim that Carrey tested positive for multiple STDs in 2013, using the name Jose Gomez for the tests.

White’s estranged husband, Mark Burton, has made similar allegations in a separate wrongful death lawsuit.

In response to Sweetman’s suit, Carrey’s attorney, Marty Singer, claimed that she had “a contentious relationship” with White, and that the two had been “estranged for years.”

“It is understandable that a mother who has lost a daughter will look for someone to blame. But in directing her grief and rage at Jim Carrey and joining this ridiculous lawyer’s attempt to capitalize on Cathriona’s suicide, Mrs. Sweetman is heading down the same dark path as Cathriona’s green-card ‘husband,’ Mark Burton,” Singer said.

“On her 30th birthday, just a few days before her suicide, Cathriona White was distraught having received a message from her mother through Facebook that was so destructive and demoralizing that she instantly deleted her Facebook account so her mother could no longer contact her,” Singer added. “Cathriona often lamented about her contentious relationship with her mother, how she was forced to leave home at the age of 15, and how they had been estranged for years.”
