The US star had made friends with the singer before her death on July 23 and she claims Amy was planning to seek help from Dr. Drew Pinsky for her addictions.
It's claimed Amy had spoken to Janice and Dr. Drew shortly before she was found dead at her home in London.
Dickinson said to Extra: 'She was desperate and her life had become suddenly unmanageable and she wanted to see if I could help her.'
Dr. Drew also confirmed the calls and added: 'Janice Dickinson, several times on my HLN program, claimed that she gave Amy my number, and that she was reaching out.'
