‘Frank Sinatra’s My Dad, But He Refused To See Me!’

Frank Sinatra's forgotten daughter Deana

She was born into showbiz royalty, but the forgotten daughter of FRANK SINATRA is bitterly asking her dead dad, “How could you have done that to me?!”

Now 57-year-old Deana Sinatra is telling her story of love rat rejection by the very leader of the Rat Pack.

It began when her mother, Hungarian actress Eva Bartok, met Ol’ Blue Eyes at a party in 1957.

Frank’s marriage to second wife Ava Gardner was ending at the time, and Eva was divorced from her fourth husband, German film star Curt Jürgens.

Eva then fled to London after discovering she was pregnant, and used her ex-husband’s name on the birth certificate.

But that couldn’t stop the Hollywood rumor mill – as Eva learned when Cary Grant first met her blue-eyed daughter.

The actress later admitted: “She came toddling in the room, and he said, ‘You can’t kid me. Frank is one of my best friends.’”

Deana grew up knowing Frank was her father, but claimed the crooner shunned her requests to meet.

“I don’t think he was a man of high morals and values,” said Deana, now a divorcée and mother of two living in Australia.

She tried to follow in her mother’s acting footsteps, using the name “Deana Jürgens.”

Her mother died in a London hotel in August 1998 at age 71 – just months after Frank passed away.

Today, Deana listens to her father’s classic songs, but said: “I can’t watch any of his movies past about five or 10 minutes because I get really pissed off at the TV screen. You know, ‘How could you have done that to me?!’”
