Jim Carrey is currently mourning the death of his girlfriend, 30-year-old Cathriona White, who was found dead of an apparent suicide at her Sherman Oaks, California, residence on Monday night.
"I am shocked and deeply saddened by the passing of my sweet Cathriona," the 53-year-old actor said in a statement to ET. "She was a truly kind and delicate Irish flower, too sensitive for this soil, to whom loving and being loved was all that sparkled. My heart goes out to her family and friends and to everyone who loved and cared about her. We have all been hit with a lightning bolt."
Carrey and White -- a makeup artist and photographer who hailed from Tipperary, Ireland -- were first linked together in 2012, when they were spotted walking on the beach in Malibu, California on Sept. 15 of that year.
But by March 2013, the actor confirmed they had broken up. "I did go out with an Irish girl," Carrey told the Irish Independent. "We're not seeing each other anymore. But she is lovely."
Still, the two obviously kept in touch and continued to date on and off over the next few years. On March 8, 2015, they were spotted having dinner together at Katsuya restaurant in Brentwood, California, prompting many to believe they had reignited their relationship.
This was confirmed by May 18, when they held hands walking together in New York City.
On May 21, Carrey made an appearance on the finale of The Late Show with David Letterman, when he brought White along.
The pair was still going strong last month, when they took a vacation together to Bancroft, Ontario. White shared plenty of scenic shots from the trip on her Instagram.
Meanwhile, Carrey tweeted a photo that White took of him while in Canada on Sept. 1, writing, "Your true self is unfathomably immense, and I mean that as a compliment. ;^P (photo by Cathriona White)."

The comedian's most recent tweet on Sept. 16 is actually another photo that White took of him. "Grand Central, NYC. ;^} (photo by Cathriona White)," he tweeted about the black and white shot.

The couple was spotted together at Gracias Madre in Los Angeles on Sept. 18, when she also posted a photo from the vegan restaurant. A source at the restaurant says they seemed like a couple, holding hands at one point. "They looked happy," the source adds. "Very polite and really sweet."
White kept her relationship with Carrey private, sharing no photos of the two together on social media, except of his hiking boots on their Canadian getaway. Her last few social media posts, however, have been cryptic. She Instagrammed a photo of a vase of flowers on Sept. 23, quoting the Irish poet W.B. Yeats. "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. W.B. Yeats," the caption read.
On Sept. 24, a goodbye message was posted to her Twitter account.
"Signing off Twitter, I hope I have been a light to my nearest and dearest. ✌🏼️❤️ to yo all," it read.

Officials tell ET White may have died of a possible overdose, and that a note was also found when she was pronounced dead at the scene. Her cause of death is being investigated as a suicide and an autopsy is likely.
