Jim Carrey claims his late ex-girlfriend's mother said she was suicidal and asked him to buy her a house

According to TMZ, Brigid believed she was being blamed for Cathriona's death because of a "horrific and degrading" Facebook post she'd left on her daughter's birthday.

And Jim alleges she told him, "I am on the point of killing myself," and asked him to buy a new house for her.

But when the 'Mask' star declined, he claims she "became angry and bitter".

In the documents, Jim's lawyers have accused Brigid of filing her lawsuit for financial gain, claiming she never loved her daughter and "she loves only money."

Despite claims the 54-year-old star gave his former lover a sexually-transmitted disease, Jim's documents state Cathriona "profusely apologised for those accusations when they got back together in 2014," and added he believed she made up the claims because she was upset when they split up.

In the paperwork, the 'Dumb and Dumber' star said: "I loved her face. I loved her Irish voice. I loved the way she smelled."

He also included pictures that documented their "beautiful 10-month relationship" which was "filled with sweetness, caring and affection".

But a lawyer for Mark Burton - Cathriona's husband, who has also filed a wrongful death suit - and Brigid hit out at Jim's filing, claiming he is a "fraud".

They said a statement: "Earlier today, Jim Carrey filed a baseless motion with the court as part of his continued attack on a grieving mother. His conduct is disgusting and dishonest. Who attacks a mother of a dead girl?

"Carrey and his "fixer" lawyers are trying to deceive the media and the public. They are making up facts they know to be untrue in an effort to save Carrey's career, which was over when he lied about not having STDs.

"Why will they not release the 2013 STD test results that Carrey took under the false name "Jose Lopez"? They should release the results and let people decide for themselves who lacks credibility.

"Carrey is a fraud and when he is forced to testify under oath, the ugly truth will be laid bare. We are confident that the court will see through the nonsense Carrey is peddling."
