Judy Garland’s daughter inherited her mother’s singing and acting abilities, as well as her battle with drug addiction.

Lorna spoke about Judy’s drug and alcohol abuse in a new interview with Studio 10, which led to her death in June 1969. “The highs were incredibly high, but the lows were devastating,” Lorna, Judy’s third husband Sidney Luft’s daughter, stated. “I learned about the disease of addiction.”

Lorna, who went on to become an actress and singer in her own right, grew up knowing about Judy’s addiction, stating that she would substitute sugar for her mother’s prescription pills.

‘I was taught how to do that by my dad. When you have a parent who’s teaching you how to take care of your other parent, that’s what you do’, Lorna told the Channel 10 show.

While the 64-year-old said her family’s house was usually full with celebrities when she was a kid, she recounts calling Frank Sinatra her “uncle” and not thinking much of it.

“Everybody was a movie star. But I didn’t know that. I just knew they were friends of my parents. I didn’t think anything of Frank Sinatra, or Humphrey Bogart, or Dean Martin or Sammy Davis or anything – they were just my uncle Frank, you know, that’s who they were,” she admitted.

Lorna also discussed her tumultuous connection with half-sister Liza in the honest conversation.

“We’re sisters, we’re going to have different opinions on different things,” she said, adding, “My sister and I always find our way back to one another no matter what comes into being.”

Lorna’s own life has been a roller coaster, with her own addiction forcing her to seek treatment at the Betty Ford Center.

She remembered using cocaine and thought it wasn’t the same circumstance as Garland’s.

“Somebody came up to me and said, ‘Do you not think that maybe you’re doing the same that your mom did?’ And I said, ‘Oh, no no no. She had a problem. I only do it at night,’ ” she admitted. “Stupid.”

Luft began to embrace her mother’s legacy, singing the songs Garland made famous whenever Luft was on tour, after years of avoiding “any song that had the word ‘rainbow.'”

Luft said of her mother, “She is on my shoulder every single day, watching over me.”
