Luann de Lesseps, 57, wears a sexy white bikini on vacation with the mystery man: The photos

Luann de Lesseps escaped the New York cold when she hit the beach in Miami. The Real Housewives of New York City star, 57, looked gorgeous in a skimpy white puka shell bikini as she strolled along the beach.

Luann showed off her fabulous figure in a cleavage-revealing white triangle top and paired it with matching cropped pants with puka strands down the sides. She accessorized her white bathing suit with a long beaded necklace, a brown leather handbag, and oversized black sunglasses.

Not only did she flaunt her figure on the beach, but she was also seen hugging a mystery man. The mysterious man wore a red short bathing suit with a black baseball cap and glasses.

Luann is having a great time in Miami and posted a photo slideshow on her Instagram. One photo of her is of her in a white bikini, while the second photo of her was of her and a girl. Meanwhile, the third photo showed Luann posing with Denio WoodMiami architect and interior designer.

In the photo, Luann wore a beige straw hat with a black bow around it and a brown and white striped crop top. The short-sleeved top had a plunging neckline and tied in front just below her chest. She paired the cropped shirt with a long beaded necklace and showed off her toned abs and slim waist.

Luann posed with Denio as they went out to eat and sat at a table in the restaurant. Denio wore a white linen shirt and sunglasses while Luann and Denio had big smiles on their faces.
