Jennifer Aniston Still Mum About Mom

Jennifer Aniston says that she and her estranged mother, writer-photographer Nancy Aniston, are still not on speaking terms five years after the elder Aniston wrote a book about her relationship with her daughter.

"I never thought my mom would not know my husband," says Aniston, 34, referring to Brad Pitt (to whom she has been married since July 2000), in an interview set to air ABC's "Primetime Thursday."

The Associated Press secured advance quotes from the TV appearance, which Aniston made to promote her new comedy with Ben Stiller, "Along Came Polly."

The actress says she and Nancy Aniston haven't been close since her mother granted an interview to a tabloid TV show and penned a book about their relationship, titled "From Mother and Daughter to Friends: A Memoir."

"She made a mistake ... I don't think she knew any better -- obviously," says Jennifer.

In publicity materials at the time of the book's release, it was described by its publisher as a "tender, poetic, and charming memoir (that) represents a healing exercise, and most importantly serves as an example of how to cope with and understand estrangement between parent and child."

But the book's message certainly has not worked to reunite Jennifer and Nancy Aniston, at least so far.

"I've definitely tried," Jennifer tells ABC of an attempt at reconciliation with her mom. "I made the efforts, and I've sort of started ... you know, it's that stubborn thing of, 'Well, I tried ... I tried enough. Now it's your turn.'"
