Courtney Love believes a very famous actor could be the grandfather she never got to meet

Is Courtney Love the long-lost granddaughter of actor Marlon Brando?

According to Page Six, the rocker’s estranged grandmother, author Paula Fox, died last week without revealing the identity of Love’s grandfather.

Love’s theory comes from the fact that Brando and Fox were both living with Stella Adler in 1943, when Love’s mother was conceived.

“[Fox] went to her grave still not telling me and my brothers and sisters who is grandpa . . . I’m sticking with Brando. It’s very probable,” Love reportedly wrote on Facebook. “I once asked Warren [Beatty] to ask Marlon to tell me. I’ll save the results of that interaction for my memoir.”

She previously claimed, “If you look at me before my first nose job, I kind of look like Marlon Brando.”
