In his unfinished memoir, "Judy and I", Luft discloses new details about their less-talked about bond and that Monroe had once sought Garland's help before she died from an accidental overdose in 1962, reported People magazine.
Luft writes that Monroe's death was "especially troubling to Judy since Marilyn had been one of Judy's telephone pals during her years of insomnia".
The book also includes an excerpt from an article penned by Garland about Monroe for 'Ladies Home Journal' in 1967, in which she talks about a haunting conversation she once had with the legend.
Monroe was sure Garland would understand her situation.
To this Garland said, "Maybe I would. If you're scared, call me and come on over. We'll talk about it."
But they never had that conversation.
