O’Connor accuses her late mother of physically and sexually abusing her, CNN reports.

"She ran a torture chamber," O'Connor says. "She was a person who took delight in hurting you."

When Dr. Phil asks her what she loved about her mother, who died in a car accident when O’Connor was a teen, the singer responds: “What I love about my mother is that she’s dead.”

On Jimmy Kimmel Live, McGraw told the late-night show host that it was O’Connor who reached out to him for help.

"She called and she said, 'I want to destigmatize mental illness,' " he said. "She said, 'I clearly have a problem, too many musicians are dying. I want to use my life, be a teaching tool. I'm willing to sit down and talk.' "

The Sinead O’Connor interview is set to air on The Dr. Phil Show on Tuesday.
