Conchata Ferrell who played the fierce and outspoken housekeeper 'Berta' in "Two and a Half Men" passed away at the age of 77.
The actress died on Tuesday due to complications from a cardiac arrest, reported by Variety.
The actress was hospitalized in May and spent more than four weeks in the ICU, where she went into cardiac arrest at one point. The actress was relocated to a long-term treatment center, where she was put on a respirator and dialysis.
Sheen paid tribute, describing the late star as "an absolute sweetheart, a consummate pro, a genuine friend [and] a shocking and painful loss".
He wrote: "Berta, your housekeeping was a tad suspect, your 'people' keeping was perfect."
Ferrell, who was known to her castmates as Chatty, earned two Emmy nominations for her role on the series, about hedonistic jingle writer Charlie Harper, his uptight brother Alan, and Alan's son Jake.
As well as Sheen, she acted opposite Jon Cryer and Angus T Jones. Cryer remembered meeting her for the first time. "She was a beautiful human, Berta's gruff exterior was an invention of the writers," he tweeted.
"Chatty's warmth and vulnerability were her real strengths. I'm crying for the woman I'll miss, and the joy she brought so many."
