Cathriona White, a stunning 28-year-old who's dated Jim Carrey in recent years, has killed herself from a purported drug overdose, RadarOnline.com has learned.
White, according to online reports, left a note in the Los Angeles home she was found in which directly referred to the A-list comedy actor -- and that they two had recently ended their relationship last Thursday.
In a jarring tweet she sent on that day, White, a make-up artist of Irish origin, wrote: "Signing off Twitter, I hope I have been a light to my nearest and dearest."
The two initially began dating three years ago, and had gotten back together as recently as this past May.
Insiders told us of White in 2012 that she hailed "from a very small rural village in County Tipperary and left Ireland for Los Angeles after studying to be a beautician.
"Cathriona is ambitious and is working as a make-up artist in Hollywood – and she's already worked on many film sets since arriving in the States. She's very focused on making this work and will do anything she can to make sure she's successful."
In what might be an eerie predictor of future anguish, the source said that the emotional White was "definitely living in a dream world" in her initial time dating The Cable Guy star.
