Diane Keaton's hidden message for kids in last song laid bare

Diane Keaton prepared a comforting “goodbye” for her children during her final months.

The actress, who passed away on October 11 at the age of 79, was aware that her time was near so left “soft” music like a “comfort blanket” to console her "soon-to-be-grieving" family when she would no longer be there, via Radaronline.com.

For the unversed, The Annie Hall star, made her first and last solo song First Christmas late last year which she co-wrote with close friend Carole Bayer Sager

As per a close source, who had worked with Keaton, the late star used to tell her pals that she "knew her time was coming" and wanted to leave "something soft and lasting" for her children.

"Diane told us this song wasn't just about loss – it was about love surviving it. She said, 'When I'm gone, I want them to play it and feel me still singing to them.'"

A second insider said of the actress, "She was so thin at the end, but still had her glow and twinkle in her eye. She called the song her comfort blanket – a way to hold her kids when she couldn't. Working on First Christmas together was her way of saying goodbye without saying it."

Notably, Sager also recalled being “stunned” by Keaton's weak appearance in her final weeks.

The lyrics of Keaton’s last and only song reads, "Now I wish that I could let go, it's a silent night, it's another year, the first Christmas without you here."
