Recovering alcoholic Butler lost her job on TV comedy Grace Under Fire in 1998 after struggling with a prescription drug problem, and her life spiralled so out of control she ended up homeless and broke.
As she began to rebuild her life, she managed to buy a farm outside of Atlanta, Georgia, but when she lost the property last year (12), she decided to head back to Los Angeles and give her career one last shot.
She hired a manager, Mark Burg, who happened to count Sheen among his clients - and the actor decided to take a chance on Butler by offering her a small role as a bartender on his new TV sitcom Anger Management.
The job has given Butler a second try as an actress and she is doing her best to impress.
She tells the New York Times, ""I'm just trying to show up and be a good worker. It does feel a little bit like being on probation, but that's not necessarily a bad thing. I'm grateful just for the shot.""
And Sheen admits he sympathised with the veteran actress' situation following his own public meltdown, which caused him to be fired from Two and a Half Men by creator/producer Chuck Lorre - the same man who axed Butler from Grace Under Fire.
Sheen says, ""She's awesome. Seriously, I think she's forgotten what a comedic genius she is.
""Somebody we have in common (Lorre) tried to extinguish that flame. And it didn't work. That kind of talent never goes away, you know? I always tell her: 'Don't forget who you are. Don't forget how good you are.'""
