Legendary actress and singer Liza Minnelli has reportedly checked into a rehab facility for substance abuse.

According to TMZ, a rep for Minnelli commented on the situation, saying she is currently making "excellent progress," confirming her stay in a treatment facility. Her spokesperson, Scott Gorenstein, said to PEOPLE, "Considering she's doing so well, we expect that she'll be out shortly." While the treatment center Minnelli is in is allegedly in Miami, the name of the place has not been released.

Her rep went on to say (via Yahoo!), "Liza Minnelli has valiantly battled substance abuse over the years and whenever she has needed to seek treatment she has done so." In an interview with the Guardian that took place in 2008, Minnelli talked openly about her addiction, saying, "My whole life, this disease has been rampant. I inherited it, and it's been horrendous, but I have always asked for help."

Minnelli was first treated for addiction to both alcohol and prescription drug abuse back in 1984 -- paralleling the drug abuse her mother, Judy Garland, suffered before ultimately dying of a sleeping pill overdose in 1969. A friend of Minnelli's commented on the situation at the time, saying (quote via PEOPLE), "She's living her mother's career all over again – being the biggest star in show business, peaking out in films, the weird marriages, the pills, the booze."

In a 2009 interview with Dateline, Minnelli spoke about her addiction again, saying, "I mean, get away from the influence for a minute and you know you have a choice. And here are the good things about it. This is a huge thing, this disease, but you can fight it with information and with clarity."
