Frank Sinatra's daughters TINA and NANCY are still bitter about their father's fourth wife BARBARA, and will never forgive the way she treated them.

The former Las Vegas showgirl was married to Sinatra from 1976 till his death in 1998 and enjoyed a frosty relationships with her stepdaughters.

Tina lashed out at her stepmother in her memoirs MY FATHER'S DAUGHTER, and Nancy admits she has blocked Barbara completely out of her life.

She says, "I never thought I would have a hate list in my life, but I have one now.

"They say, 'Forgive.' No thanks. I said to Dad once, 'I don't think we exist for her.' He said, 'You may be right.'

"So there is a list of people who don't exist for me."
