Cathriona White, Jim Carrey‘s on-and-off girlfriend, has died in an apparent suicide at a Los Angeles home.
On Tuesday, Carrey issued an emotional note saying he’s “deeply saddened by the passing of my sweet Cathriona” — and also honored the woman he’s been linked to for the past three years.
“She was a truly kind and delicate Irish flower, too sensitive for this soil, to whom loving and being loved was all that sparkled,” Carrey said in a statement obtained by PEOPLE. “My heart goes out to her family and friends and to everyone who loved and cared about her.”
The Irish native, 30, was “pronounced dead at 8:40 p.m. last [Monday] night at a residence,” Los Angeles Assistant Chief Coroner Ed Winter tells PEOPLE.
Although White’s official cause of death cannot be determined until an autopsy is conducted, Winter said there were indications at the scene of a suicide.
“It was reported as a possible suicide. There evidently was a note found. There were pills located near her,” said the spokesman, who added that the “final cause of death won’t be released until we get full toxicology and tests back.”
According to the Irish Independent, White – a native of the Tipperary region of Ireland – and Carrey, 53, first met on a film set in 2012. They reportedly dated for most of 2013 before reuniting earlier this year.
In May, the pair were spotted walking hand in hand in New York City. However, TMZ reports the pair recently split again.
White seemingly issued her final Tweet last Thursday, which read in part: “Signing off Twitter, I hope I have been a light to my nearest and dearest.”
The Irish native worked as a makeup artist and lived in Sherman Oaks, California, at the time of her death.
She was also active on Instagram, where just last week she posted two images from a belated birthday dinner at Nobu Malibu.
“Before going for a wonderful belated birthday dinner at Nobu in Malibu last night,” she wrote beside a selfie.
But a post from five days ago hinted at her inner struggles.
The image showed an elegant floral display, accompanied by a forlorn quote from the poet W.B. Keats: “Faeries, come take me out of this dull world, For I would ride with you upon the wind, Run on the top of the dishevelled tide, And dance upon the mountains like a flame.”
Carrey also credited White with snapping two photos posted on his Twitter feed.
