Cathriona White - the on-again, off-again girlfriend of actor Jim Carrey - has reportedly committed suicide. She was 28 years old.
TMZ is reporting that White left a suicide note that mentions that she and Carrey broke up on September 24.
That same day, White deleted her Twitter account, but not before posting a final tweet that read, "Singing off Twitter, I hope I have been a light to my nearest and dearest."
Sources say Carrey and White first met in 2012, shortly after Carrey broke up with Jenny McCarthy. They dated for several months and then went their separate ways.
The two rekindled their romance back in May and broke up again just last week.
White reportedly overdosed on prescription drugs. According to police, her body was discovered by two friends late last night.
It's unclear how serious the relationship between White and Carrey was, or if there were other factors involved in her decision to take her own life.
Reps for Carrey have thus far declined to comment on the situation.
A native of Ireland, White moved to Los Angeles to work as makeup artist. Insiders say she met Carrey shortly thereafter, and the pair instantly hit it off.
