During their conversation, she recalled the moment she thought she was going to die from an overdose.
She told the host: "I remember timing my heart because I knew it was going to stop… [starts crying].
"I remember my telephone was there and I remember crawling on my hands and knees to pick up the phone and call, and then I woke up in hospital.
"I remember saying my prayers. I knew my heart was stopping."

The star then headed to a rehab facility in Arizona and admitted that she was no longer interested in drugs.
Tara explained: "I don't have any temptation to take drugs any more. No, no, gosh no. Drugs absolutely terrify me."
She went on to reveal that she became "a recluse" and avoided heading out to events, adding: "I get terribly anxious going out, I've only been out three times this year.
"I don't go out to public events. For the last two years I haven't worked. I've seen a therapist every single week for the last nine, 10 years of my life."
