North Carolina mom Shelly Wright believes she was conceived during her mother’s one-night stand with ’70s heartthrob David Cassidy of TV’s “Partridge Family.”

But Cassidy, 64, has rebuffed Shelly’s repeated attempts to contact him, and the former teen idol’s publicist gave Shelly the runaround when she requested a DNA test.

Shelly, 40, insists that she isn’t looking for money. Her only wish is to connect with the man she hopes is her biological father.

Now she’s turned to The National ENQUIRER for help. Here is her heartbreaking plea:

This is my cry: that the truth be revealed! All I want is to find my father – my real father.

Growing up, I never looked like the man who was raising me as his daughter – and my whole family talked about it.

Finally, I confronted my mother. She revealed that she’d had a one-night stand with David Cassidy in Nashville in 1973.

When I Googled him, I realized that I looked amazingly like David, and his daughter Katie.

For two years, I kept my story secret. But my whole being yearned to know the truth, and I reached out to David’s publicist.

I asked her to set up a meeting with David when he performed near my home. But she refused.

Eventually, the publicist agreed to have David to submit to a DNA test. But she tricked me with a fake test.

After that, I contacted David’s son Beau through Twitter.

Beau said that he’d help get David to agree to a DNA test. So I sent him a DNA kit. But Beau hasn’t gotten back to me. 

Someone said to me, “Shelly, you’re 40, get over it.”

But for me, “getting over it” is not an option. Something deep inside is urging me to push on and find the truth.

So I’m reaching out to David through The National ENQUIRER.

This is not a gimmick. It’s not a game. I’m frustrated and desperate, and I just want David to know that I’ve been trying to contact him.

And I’m not trying to embarrass anyone. It’s not my fault David is a celebrity. 

Everyone deserves to know who their father is – even if that man is famous.

And this isn’t about money or fame.

My husband has a good job. We have a good life.

A well-known daytime talk show offered me a lot of money to tell my story. But I didn’t do it – because my quest is to find my father. That’s all.

From the bottom of my heart, I’m begging David Cassidy – the man that I believe is my father – to agree to a DNA test.

Then, and only then, will I find the truth.
