Cathriona White, the on-again-off-again girlfriend of actor Jim Carrey, was found dead Monday after an apparent drug overdose in a residence in Sherman Oaks, California.

“Cathriona White was found deceased in a residence and pronounced at 8:40 p.m. last night in the 1500 block of Briarwood Drive in Sherman Oaks,” Ed Winter, Assistance Chief L.A. Country Coroner’s Office told TheWrap on Tuesday. “It was reported as a possible overdose. Her autopsy is pending. There were some pills found.”

Carrey, 53, and White, 28, first started dating in 2012 but broke up shortly after. In May, they were seen together, allegedly rekindling their romance.

On Sept. 24, White posted her last tweet, in which she wrote, “Signing off Twitter, I hope I have been a light to my nearest and dearest.”
