The former Playboy model - who dated the 89-year-old magazine publisher for seven years - alleges she found a copy of his will, which said she was entitled to the hefty sum of money if she continued to stay in the house.
She said: ''It was very clear to me that he'd left that out for me to see, because he was hoping it would change my mind and get me to stay.
''It just kinda disgusted me more than anything because all he can do is say, 'Oh, here, I'm gonna throw you some money to get you to stay.' It just grossed me out.''
Speaking in an interview for Oprah Winfrey's Where Are They Now?, she added: ''Hef and I started hitting kind of a rocky patch when it became clear that Bridget and Kendra were leaving, they were moving on to new things.
''I just had enough and just realized all these delusions I'd been under and that this was no longer the life for me.''
