Luann de Lesseps’ PDA-filled Cancun vacation with boyfriend

Luann de Lesseps slipped into a little yellow string bikini for a PDA-packed day in sunny Cancun, Mexico.

The “Real Housewives of New York City” alum was pictured embracing and making out with boyfriend Michael Riemerschmid on Monday as the pair enjoyed a romantic vacation.

De Lesseps, 60, beamed while holding hands with her silver fox boyfriend, and she was later seen plunging into the turquoise waves to cool off.

The Bravo star — who accessorized with a delicate pair of earrings and went makeup-free for the beach outing — smiled radiantly while snuggling with her man in the water.

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.
