Shocking new details about David Geffen’s estranged husband, David Armstrong, have been revealed by his family and ex-girlfriend.

The former go-go dancer’s adoptive father, Patrick Armstrong, claims he learned about his son’s forthcoming divorce from the billionaire businessman, 82, from the media.

“I don’t know where he [David] is, or what the situation is, first I heard about it [was] one of my sons saw it on TV,” he told the Daily Mail.

“We kinda didn’t even know about the marriage. But 50 years is a big age gap,” Patrick, 68, added of the couple’s huge age difference.

“I don’t know how you expect it to work out. My soon-to-be former son-in-law is older than me.”

Patrick told the outlet that he wasn’t invited to David and the film producer’s 2023 nuptials and that he last saw his son two years ago at a family reunion. At the time, however, the 32-year-old allegedly didn’t mention he had gotten married.

“For some reason, I Googled his [my son’s] name, and that’s when it came up,” Patrick shared. “I never expected I could Google one of my kids’ names and have them show up.”

Patrick revealed that he had never met Geffen, but also looked him up on the internet.

“Some of the stuff I looked up, it kind of sounds like Geffen is a little overbearing. But you can’t believe everything you read. I can’t really have an opinion of him,” he said.

Patrick told the Daily Mail that he allegedly had to go through Geffen’s business secretary to contact his son by phone and then “David [would] get back to us.”

Though he said David regularly kept in touch with his older sisters, Patrick claimed his son “got quiet” a few months ago.

Patrick — who adopted David and 13 other kids with his wife after they had two biological kids — said the model’s siblings “were happy” for his marriage.

“Evidently, it looks like it didn’t work out, which would have been my thing at the beginning, because it’s too big an age difference,” he said. “I don’t know how you can fall for someone 50 years older than you, because you don’t even have the same stuff in common, stuff you grew up with.”

Patrick admitted that he was “surprised” his son even got with Geffen, noting that David “didn’t seem to be interested in boys.”

The dad of 16 told Daily Mail he’s unsure if David will reach out amid the divorce.

“We’re just kind of waiting now to see if he mentions it, bring it up on his own terms,” he explained.

David’s ex-girlfriend also shared some insight into their past. The woman, who remains anonymous, told the outlet that she believes David’s romance with Geffen was “kind of typical.”

“I just think he got what he was looking for. He cared a lot about the money, in my eyes. He always wanted to become rich and famous,” she claimed.

“He wanted the name brand stuff — the cologne, the sunglasses, the shoes. He wanted to be a public figure. He had big dreams,” David’s ex alleged.

The woman said she was surprised by news of the divorce because there was “quite an age gap.”

“I sure as hell am not marrying someone 50/60 years older than me, so I can watch them die,” she shared, adding that she was “proud” of Geffen for divorcing David before he passed away to prevent him from getting his “entire [fortune].”

Earlier this month, TMZ reported that the record company founder, who has a net worth of more than $9 billion, filed for divorce from David after two years of marriage —  with no prenuptial agreement in place.

Geffen cited irreconcilable differences as the reason for the split and has hired attorney Laura Wasser to represent him in the split.

Though Geffen has amassed his wealth through founding several record companies, including Asylum Records, DreamWorks Records, DGC Records and Geffen Records, he has been retired for 15 years and most of his income now consists of equities and stocks.

TMZ reported that California law states dividends from stocks are separate property, which means David may not get much in the divorce.
