The longtime, on-again-off-again girlfriend of Jim Carrey, Cathriona White, 28, was found dead from an apparent suicide just days after the couple split, TMZ reports.

“Our sources say White left a suicide note addressed to Carrey which references their breakup on Sept. 24. Cathriona tweeted on the 24th... "Signing off Twitter, I hope I have been a light to my nearest and dearest,” TMZ Reports. “Law enforcement tells us they believe she died from an overdose of drugs -- pills were next to her body. We're told 2 friends found Cathriona last night when they went to check on her.”

Carrey, 53, met White in 2012. The couple split but reportedly rekindled their romance this past May. 

Carrey told Entertainment Tonight that he's "deeply saddened," and said this: “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."
