David Cassidy’s Secret Daughter Blasts Family

David Cassidy left behind a “secret” daughter — and now she's furious with his family for refusing to help her find out the truth about the dead "Partridge Family" star!

Heartbroken Shelly Wright believes she was conceived during her mother’s one-night stand with the troubled ’70s heartthrob who found stardom on the pop charts. Now she's told The National ENQUIRER that she’s determined to continue her long fight to confirm that the pop star — who passed away in 2017 at age 67 — is her biological dad.

“I’m angry because I didn’t have the opportunity to meet him,” Shelly told The ENQUIRER in an exclusive interview. “It’s selfish of his family for not taking me seriously. Now he’s gone, and I’ll never get a chance!” Shelly had been raised by her mother, Donna G. Wallace, and Nashville songwriter James Bohon. But as a child, she always doubted Bohon was her real father.

“I didn’t look anything like him, and my whole family always talked about it,” Shelly recalls. Finally, Shelly confronted her mother — who confessed that she believed Cassidy had fathered Shelly during a drunken one-night stand. Desperate to learn the truth, Shelly reached out to the faded pop star several years ago, but says she got the runaround when she requested a DNA test.

David’s son Beau allegedly offered to help Shelly in 2013, according to Twitter messages obtained by The ENQUIRER — but that also went nowhere. Despite that, Shelly says: “I’m still pursuing a DNA test. I want to know where I’m from!” Shelly's also now motivated by David's tragic death — after he revealed that he was fighting dementia shortly before he died of organ failure.

“I want to understand the medical history,” Shelly (at right) told The ENQUIRER. She also insists she’s not after the singer’s estate. After filing for bankruptcy in 2015, David died with only $150,000 in assets. His will left that amount to son Beau while cutting out his estranged daughter, actress Katie Cassidy — with the two having had a rocky relationship after Katie was raised primarily by her mother, model Sherry Williams.

“I can’t believe he did that to Katie,” said Shelly, who lives in Naples, Fla. “But I do not want or need his money. My husband has a great job — and I don’t want anything from his family, either. I’ll pay for the DNA test! I know without a shadow of a doubt that David Cassidy is my dad — and all I want is the truth!”
