Jim Carrey's ex-girlfriend found dead

Jim Carrey's former girlfriend Cathriona White (r) has reportedly committed suicide.

Jim Carey is "shocked and deeply saddened" by the death of ex-girlfriend Cathriona White.

The 53-year-old actor has paid an emotional tribute to the 30-year-old Irish beautician after she was found dead at her home in Sherman Oaks, California yesterday.

In a statement, the Kick-Ass 2 star said: "I am shocked and deeply saddened by the passing of my sweet Cathriona.

"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."

The brunette beauty died from a suspected suicide and reportedly left a note.

Los Angeles Assistant Chief Coroner Ed Winter told the Independent : "Ms White was found at 8.40pm local time on Monday, September 28, (Tuesday at 4.40pm NZT) at her home in Sherman Oaks.

"The final cause of death has not been confirmed, pending an autopsy."

The on-again, off-again couple first started dating in 2012 after meeting on a film set, but split a few months later.

They rekindled their romance last May, but recently ended it for the second time.

Jim last mentioned Cathriona, who moved to Los Angeles from her native Co. Tipperary in 2009, on his Twitter profile on September 16, when he credited her for taking a photograph of him standing in Grand Central station in New York City.

Cathriona was also active on social media and tweeted last week: "Signing off Twitter, I hope I have been a light to my nearest and dearest."
