TMZ has learned that Jim Carey’s 28-year-old girlfriend, Cathriona White, committed suicide Monday night.

White left a suicide note that mentioned Carey and their breakup on September 24th. The relationship was frequently on and off.


She’s said on Twitter on September 24th “Signing of Twitter, I hope I have been a light to my nearest and dearest.”

Officials think she died from a drug overdose. The two met in 2012 and dated for a few months before calling it quits. They ended up getting  back together earlier this year.

This is a developing story.
