Only in New York would the longtime New York Post gossip columnist, Cindy Adams, officially receive her high school diploma she was hoping to get back in 1946, after being denied for allegedly failing a class nearly 80 years ago.

“I’m living proof you can’t be anything if you don’t go to college,” Adams said on Tuesday.

“We had a thing for women called ‘home ec,’ — called home economics — in those days, the ladies had to sew their own graduation dress. I don’t know how to sew a goddamn graduation dress,” she said.

Instead, then-teenager Adams took the dress to a tailor, who helped complete the job. She says she was so bright; she was already on track to graduate in three years.

“We brought it to the principal, and he said, ‘You didn’t make this yourself, you can’t go to college, you can’t get a diploma, you can never, ever go anywhere,’” she added.

But that didn’t stop the newspaper woman from becoming a living New York City legend and writing countless stories about the city she loves.

She’s authored a gossip column published for over four decades in the legendary tabloid, befriending high powered individuals, and at times, holds their feet to the fire.

“The mayor [Eric Adams] comes to my house. He was just there last week. The governor [Kathy Hochul], I go out to dinner with — she comes to my house,” she told reporters.

She said her secret is to be fair and try hard.

“If you’re a reasonably good, honest person, not that I’m smart, not that I’m anything, but I’m fair and I try,” she revealed.

That’s why on Tuesday, the city Department of Education gifted Adams an honorary diploma on the site of her alma mater: the former Andrew Jackson High School in Cambria Heights, Queens.

“What everybody cherishes about New York City — it’s tough, it’s gritty, it’s sassy, it’s irreverent but there’s nothing like it. That embodies you — our living lady legend,” Gov. Kathy Hochul said, who helped introduce Adams.

The governor also gave Adams another honorary diploma on her 94th birthday, back in April.

“Imagine all of these years that we denied you of that diploma. That denial of your diploma denied us the bragging rights that we could have had, but now you have those bragging rights,” Mayor Eric Adams said, who also spoke in the tabloid legend’s honor.

The diploma is written out to Cynthia Heller — Adams’s name before it changed due to multiple marriages.
