The ex-girlfriend of Jim Carrey, Cathriona White, has died, the actor confirmed in a statement sent to FOX411.

"I am shocked and deeply saddened by the passing of my sweet Cathriona," Carrey stated. "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."

TMZ reports that White, 28, was found dead by the LAPD Monday night, and that a suicide note was found at the scene.

She last posted on Twitter on September 24: "Signing off Twitter, I hope I have been a light to my nearest and dearest."

An officer with LAPD told FOX411 the police department does not release information regarding suicides. The Los Angeles County Coroner could not immediately be reached for comment.

TMZ reports Carrey, 53, and White dated in 2012 and broke up, but they were photographed holding hands in New York City on May 21, and many news outlets reported they had rekindled their romance. 

Carrey's most recently posted a photo of himself on Twitter on Sept. 16 with the caption, "Grand Central, NYC (photo by Cathriona White)." According to TMZ, White's alleged suicide note referenced a breakup with Carrey on Sept. 24. 

White was a makeup artist who moved to the United States from Ireland. Her social media accounts, though active, make no recent mention of Carrey, although she did retweet a photo with him on Feb. 24 at what looks to be an LA Kings hockey game. Her Instagram account is filled with snaps of her recent meals, her family and animals. 

One week ago she celebrated her birthday at the popular restaurant Nobu in Malibu, posting photos at the restaurant and before the dinner.
