Luann de Lesseps sparked engagement speculation while rocking a huge diamond ring — on that finger.

The “Real Housewives of New York” alum, 60, showed off the dramatic sparkler while stepping off a teal scooter and carrying a basket of purple flowers in Sag Harbor, NY, on Monday.

In another pic, she sat on the scooter and clutched a helmet while applying lip gloss as the ring — which appeared to be a multi-carat emerald cut sparkler — glinted in the sun. She added layered necklaces to her jewelry glam.

De Lesseps wore a green crop sweatshirt and jeans, paired with sneakers for the outing, during which she was also snapped buckling the helmet, flaunting her brunette locks while removing it, and prominently displaying the weighty piece of jewelry.

RB reached out to reps for the TV personality but did not receive an immediate response.

It is unknown if de Lesseps — who is twice divorced — is currently in a relationship with anyone.

The Bravolebrity was last linked to “Southern Hospitality” star Joe Bradley after an eyewitness told Us Weekly that the reality stars were “all over each other” at the Dream Hotel in New York City in January 2024.

The pair allegedly visited the venue after “getting flirty” during a pre-taped episode of “Watch What Happens Live with Andy Cohen” earlier in the evening.

However, a source told RB at the time, “this is just a rumor and is not true.”

Bradley also denied the rumors. “This is the truth: Me and Luann got a drink, and we hit it off,” he said during the Season 2 “Southern Hospitality” reunion in February 2024.

While confessing he was “probably was too flirtatious” with de Lesseps, given that he was still involved with “Summer House” personality Danielle Olivera at the time, he insisted they “did not hook up.”

“I did cross a line at the hotel, but I did not kiss her,” he divulged.

De Lesseps also revealed in February 2024 that she was dating a model.

“I actually had a date last night with a guy that’s 62 years old but really attractive,” she told Derek Zagami in a clip shared to his Instagram at the time. “He continues to model to this day — does very well.”

De Lesseps described the unnamed man as a “husband commercial type of guy but very nice.”

She was also linked to her Gersh agent Richard Super after she began secretly dating him in 2018.

“He’s smitten with her,” a source said at the time, “and she’s very excited about it.”

De Lesseps married the man who would make her a Countess — Count Alexandre de Lesseps — back in 1993. 

Though it was an experience she later called “a fairy tale, too good to be true,” the couple would split after 17 years of marriage, during which they welcomed children Victoria, now 30, and Noel, now 28.

The Bravolebrity married her second husband, Tom D’Agostino Jr. on New Years Eve 2016, but they parted ways less than a year later.

“It’s with great sadness that Tom & I agreed to divorce,” she tweeted via X in August 2017. “We care for each other very much, hope you respect our privacy during this sad time!”
