When asked about daughter Frances Bean, 17, who currently has a restraining order against her mom, Love points a finger at the family of her late husband Kurt Cobain.
"Those snarly-ass O'Connors want checks," she says in Spin slated to hit newsstands Feb. 23, referring to her late husband's family. "I'm through supporting their asses."
Cobain's mother, Wendy O'Connor and his younger sister, Kimberly, currently have legal, medical and financial authority over the teenager.
Despite losing legal control of Frances Bean, Love, 45, says she's focused on making her new album, Nobody's Daughter, a success.
"One time, Frances was being mean and said, 'What are you going to do if the record fails?' " Love reveals. "Well, Frances, it can't fail because I love it, and I've worked really hard to make sure that I love it."
But, the magazine reports, Love is not as gruff as she sometimes seems and tears up at the mention of her daughter, saying, "I'm lost in a [expletive] nightmare maze."
The singer revealed her feelings about her daughter on Twitter last week, writing, "My daughter has been kidnapped and i am going to take it? Of course i was beyond angry, despondent suicidal in every way."
However, in the Spin interview, she references suicide again while discussing drugs. "I don't take anything that isn't prescribed to me," she says. "Cocaine, narcotics – those would be tantamount to suicide, and I'm not suicidal."
