Be cool. Don’t be all, like, uncool.

Luann de Lesseps tried to upstage her “Real Housewives of New York” frenemy Carole Radziwill after she landed the front page of Friday’s New York Post.

The cabaret star posted a photoshopped version of a New York Post cover to her Instagram page this afternoon, leading with the headline, “Countess Still Serving it Up: Luann de Lesseps parties, performs, and proves she’s still the Queen of New York.”

The fake issue, which was also “printed” on Friday, featured two photos of Lesseps — one of her holding a martini, and another performing onstage.

“Keep on SERVIN’ 👊🏻✨” de Lesseps wrote in the caption of the post, while taking the opportunity to advertise for her new cabaret tour.

De Lesseps and Radziwill have quite the rocky history. They fell out during “RHONY” Season 7, as Radizwill began dating chef Adam Kenworthy, who was previously in a relationship with de Lesseps’ niece, Nicole Nadeau.

It’s spanned into a years-long feud. In August, de Lesseps threw a jab at Radziwill’s return to “RHONY,” claiming that the writer made the right decision to come back, since she wasn’t “busy” doing anything else.

Her photoshopped Instagram post came as Radziwill graced The Post’s cover for her “parking menace” ways.

The Post reported that Radziwill, who parks her red Jeep on the street near her SoHo apartment, racked up over 83 traffic violations over the past four years.

She also accumulated $8,000 in tickets and used ConEd cones to try to save parking spots.

However, the “RHONY” star was tickled by her Friday cover, gushing over it in an Instagram post.

“I’m on the cover of my hometown paper?!” the reality star captioned a snap of the paper, adding that it felt like a “fever dream.”

She also responded to The Post’s reporting about her traffic violations, writing, ““I ♥️ the traffic cops. I ♥️ my city and I ♥️ the New York Post,” she continued in her caption. “(Btw, I only overslept 17 times in 6 years? I deserve a 🗝️ to the city) Beep, beep, bitches. 🚗🚗”

Radizwill added in her message that she has “paid every dollar of those tickets” and supports the Department of Sanitation.

Andy Cohen was also floored by Radziwill’s cover.

“I had to go to Casa Magazines to see if it’s real. It’s real. I can’t believe it!” the Bravo exec said in a video posted to his Instagram Story Friday, as he held an issue of the paper.

“Of everything happening in the world, Radzi’s parking is the most important thing in New York City,” Cohen laughed. “This is the most important thing.”
