Amid the sun-kissed shores of Cancun, Mexico, Luann de Lesseps exuded radiant confidence as she donned a vibrant yellow string bikini, soaking up the sun and enjoying some quality time with her beau, Michael Riemerschmid. The “Real Housewives of New York City” alum was spotted on Monday wrapped in a warm embrace with Riemerschmid, their affectionate display capturing the essence of a romantic getaway.

At 60, de Lesseps appeared to be in high spirits, her happiness evident as she strolled hand-in-hand with her silver-haired companion. The couple’s moments of intimacy unfolded against the backdrop of the sparkling turquoise waves, where de Lesseps was seen taking a refreshing dip to escape the heat.

Choosing to keep it natural, the Bravo star accessorized her beach look with subtle earrings and opted for a fresh-faced appearance, her smile as bright as the sun overhead. In the water, the couple’s chemistry was palpable as they shared a tender embrace, clearly savoring their time together.

Riemerschmid complemented the beachy scene in a stylish pair of blue swim trunks. At one point, he playfully lifted de Lesseps onto his hips, the two locking eyes in a moment that spoke volumes of their shared connection and joy.

Riemerschmid donned a pair of blue swim trunks for the romantic beach day, and at one point was seen hoisting the reality TV personality onto his hips as they gazed into each others’ eyes.

De Lesseps — who was seen modeling her flawless physique in a Burberry bikini in November — sparked engagement rumors after rocking a massive sparkler on her left hand in June.

A source clarified to Page Six at the time that she’s not engaged, and simultaneously revealed that she’s dating Riemerschmid.

“She’s not engaged,” the insider told us. “It’s not a diamond. It’s an aquamarine that one of her suitors from the show gave her. It didn’t fit right so she put it on her ring finger.”

An additional source divulged to us that she and the real estate agent are an item after he was spotted at a Hamptons event over Memorial Day weekend informing guests that he’s de Lesseps’ boyfriend.

“He was there with Luann’s daughter’s boyfriend [Andre Bojanic],” they told us, adding that “Luann and her daughter [Victoria] were at a wellness retreat for the weekend.”

De Lesseps’ former ”RHONY” co-star Dorinda Medley was DJing at the event along with the Muses, so we’re told that “Luann sent them in her place to support.”

“It was cute,” they added.

De Lesseps married Count Alexandre de Lesseps in 1993, and the former couple welcomed kids Victoria, now 31, and Noel, now 29, before parting ways in 2009.

She subsequently tied the knot with Tom D’Agostino Jr., on New Year’s Eve 2016, and they split less than a year later in August 2017.

Luann was last linked to “Southern Hospitality” star Joe Bradley after a source told Us Weekly that they were “all over each other” at a New York City hotel in January 2024.

They allegedly spied the duo “getting flirty” during a pre-taped episode of “Watch What Happens Live with Andy Cohen” earlier that same evening. However, a source told Page Six, “this is just a rumor and is not true,” and Bradley also denied cheating speculation.

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

While admitting that he was “probably was too flirtatious” with the reality star — especially since he was still in a relationship with “Summer House” star Danielle Olivera — he said he and Luann “did not hook up.”

Luann revealed in February 2024 that she was dating a 62-year-old model, describing the unnamed partner as a “husband commercial type of guy but very nice” in comments to Derek Zagami.
