Liza Minnelli has checked herself into a rehabilitation center to help her deal with her addictions, mostly to alcohol, a representative for the singer said, TMZ reported Wednesday. Minnelli was making "excellent progress" at the Malibu center, according to the report.

The 69-year-old singer had last checked herself into a rehab facility in 2004. Minnelli is the daughter of Hollywood star Judy Garland, who had died in 1969 due to a drug overdose at her rented home in London.

Minelli, who has struggled with her addiction to alcohol and painkillers, has been married four times. Alcohol played a role in her divorce from her fourth husband, David Gest, according to 2002 court documents, People magazine reported. Gest had reportedly said that during their 16-month marriage, there were abusive, alcohol-fueled incidents.

"Liza Minnelli has valiantly battled substance abuse over the years and whenever she has needed to seek treatment she has done so," Scott Gorenstein, a spokesman for Minnelli, said, according to CNN, adding: "She is currently making excellent progress at an undisclosed facility."

Minnelli had also previously checked into the Betty Ford Clinic in the 1980s, and had also sought treatment at the Caron Foundation in Pennsylvania in 2003, E! reported.

"My whole life, this disease has been rampant. I inherited it, and it's been horrendous, but I have always asked for help," Minnelli said in a 2008 interview, according to the Guardian.

In 1973, the singer had won an Oscar for her performance in "Cabaret." In 2010, she was offered half a million to participate in a reality show "Celebrity Rehab" but she turned it down, TMZ reported.
