Jim Carrey's ex-girlfriend Cathriona White, 28, has committed suicide, law enforcement sources tell TMZ.
The Irish make-up artist was found dead at her Los Angeles, California home Monday night, after two friends showed up at the residence to check in on her.
News of her death comes just five days after breaking up with the comedian for a second time.
TMZ reports, according to sources, that White left a suicide note in which she said she broke up with Carrey on September 24. That was the same day that she wrote a worrying message on Twitter.
'Signing off Twitter, I hope I have been a light to my nearest and dearest,' White wrote.
It's believed that White, originally from Cappawhite in Ireland's County Tipperary, died from a drug overdose.
The comedian had not yet commented on the passing of his former girlfriend.
The couple first met in late summer 2012 but by March the following year it was all over.
While Carrey never said why, the comedian did confirm that he had split from the former makeup artist to the Irish Independent.
He said in March 2013: 'I did go out with an Irish girl. We're not seeing each other anymore. But she is lovely.'
However, by May of this year, the couple had rekindled their romance and were seen happily holding hands on outings in New York.
In October 2012, friends from White's small village of less than 400 told the Irish Mail on Sunday how they were completely taken aback when they saw pictures of her hand in hand with Carrey, when they first started dating.
'We can't believe it,' says a former classmate of Cathriona's from the Convent of Mercy in the nearby town of Doon, Co. Limerick.
'Of all the people, you wouldn't have expected it. Cathriona was always lovely looking, but she wasn't pushy - she was very shy really and quiet.'
But she was also ambitious. White completed her Leaving Certificate at the Convent of Mercy before going on to study beauty and complementary therapies at the Limerick College of Further Education. After that, she found work as a beautician in Tipperary before packing her bags for American in 2009.
