"I didn’t feel like I had a drug problem," Minnelli said in the film, according to USA Today. "I’d drink silly drinks like rum and coke."

Minnelli developed a valium addiction following her mother's death, which led to drug problems and eventual stints in rehab. The musician most recently entered rehab in 2015.

"Liza Minnelli has valiantly battled substance abuse over the years, and whenever she has needed to seek treatment she has done so," a representative for Minnelli told E! News at the time. "She is currently making excellent progress at an undisclosed facility."

Minnelli hid her alcoholism in the ‘70s by telling people she couldn’t drink due to stomach problems.

"I didn’t want people to know I was under stress," she claimed in the documentary. "I always wanted to be the hero."
