Comedian Jim Carrey says his ex-girlfriend didn't kill herself because he gave her STDs.

Hollywood comedian Jim Carrey and his legal team have labelled the wrongful death lawsuit, which blames the actor for ex-girlfriend Cathriona White‘s suicide, a “shameful shakedown of money”.

Court documents show White’s mother Brigid Sweetman filed the lawsuit against the 54-year-old in October, and claimed Carrey “knowingly” gave her daughter three sexually transmitted diseases during their three-year on and off relationship.

Among claims that Carrey knowingly transmitted Herpes I and II, Chlamydia and Hepatitis to White “without warning” are suggestions that the Yes Man actor called White a “whore” and verbally threatened to silence her with the help of high-priced lawyers and fixers.

The accusations, Carrey says in legal documents filed on December 19, are "irrelevant" to the case and do nothing other than 'harass and humiliate' with the hope of bullying him into an unmerited settlement.

Carrey has requested a judge strike any mention of him having sexually transmitted diseases from the documents for this reason.

"A part of their attempt to shakedown Carrey for a multi-million dollar payday, Sweetman and her attorney have riddled the Complaint with severe ad hominem attacks and allegations about STDs, none of which are relevant to the cause of death," the documents read.

"None of these allegations belong in the Complaint."

Carrey's defence team argues that two of the suicide notes White left behind spoke of her ex-partner in loving terms - one describing him alone as her "family" and telling him "I love you".

"White left Carrey two suicide notes speaking lovingly to him, requesting his forgiveness for ending her own life, describing him, and him alone, as her "family", and entrusting him to divide her property," the court documents obtained by Daily Mail read.

In contrast, a third note left by White reads "Jim Carrey my blood is on your hands".

"I hope that you learn you are not god. You are not above taking consequences for your actions," the note continues.

"... I would have done anything for you and in return your actions ruined me... you destroyed my body. Which in turn destroyed my mind and self worth."

Carrey insists he is not responsible for the 2015 death of White, who overdosed on prescription medication Ambien, Percocet and Propranolol on September 28, the third anniversary of her father's death.

Sweetman's suit demands Carrey cover general damages, economic damages, funeral and burial expenses, punitive damages and attorney fees stemming from White's suicide. With it, Sweetman submitted STD tests as evidence that showed positive results for multiple diseases. Sweetman's attorney says the tests, filed under the medical alias 'Jose Lopez' on January 28 2013, belong to Carrey.

Less than one month later, on February 20, messages between the pair show that White was concerned about finding "a couple of bumps" and wanting to get "checked".

After the pair exchanged a number of texts, Carrey wrote: "I hope your [sic] ok hun. It could be from someone before me. Doesn't show up until you're really stressed."

When White told Carrey that she was tested just before the pair began dating, meaning the STDs could not have come from another man, Carrey "inexplicably" ended the relationship.

"You have become too much drama," his text message read.

Meanwhile, Carrey says that White and Sweetman had a deeply fractured relationship from the moment White left home as a 15-year-old.

In the court documents, Carrey says he and White were a "loving couple", and that Sweetman's legal action is seeking to "profit from the suicide-death of her long-estranged daughter".

"White loved Carrey, viewed him (and not Sweetman) as her family; and White was not upset with him at the time she took her own life by overdosing on prescription medication," the filing says.
