Pat Montandon, who famously dated Frank Sinatra, dies at 96

Pat Montandon, who once famously dated Frank Sinatra, has passed away at the age of 96.

The TV host and activist breathed her last on December 21, in an elder care facility in Palm Desert, Calif.

Her son, Sean Wilsey, confirmed the upsetting news via an announcement post on the socialite’s Facebook page.

“This is Pat’s son Sean writing,” he began the caption, revealing his mother has been living at De Anza House and has been attended to with great love and dignity by her friend and kind staff members.

Reflecting on the days leading up to her death, the son shared, “My mom stopped eating a week ago and stopped drinking a few days later. Her beloved longtime friend Susan Gold drove out from LA to be with her immediately. I flew out from New York yesterday and spent the night at her side. She passed away this morning but was able to see her two grandchildren, Owen and Mira Wilsey, last month.”

“Owen and Mira called and gave her their love last night, and it was clear that she heard them,” he continued. “She passed surrounded by love. I will be writing an obituary for her over the next week, and I would be grateful if you would share your memories of Pat here.”

Born in Oklahoma in 1928, Montandon was married and divorced four times and was also known for briefly dating the legendary singer.

The My Way hitmaker briefly dated Montandon during the summer of 1961 after the two first crossed paths in Palm Springs while she was a salesgirl at Neiman Marcus.

Their short-lived romance occurred while she was living in Lake Tahoe and managing a branch of the Joseph Magnin clothing store.

Despite their breakup, the Fly Me To The Moon singer remained part of her elite social circle, attending her famous roundtable luncheons and parties in San Francisco throughout the 1960s and 1970s.

Dubbed San Francisco's "Golden Girl" by the media, Montandon detailed her relationship with Sinatra, who died at age 82, in her 2007 memoir, Oh the Hell of It All.
