The RHONY mom showed off the two-piece look as well as her new backyard swimming pool.

Luann de Lesseps has blessed her fans with another incredible swimsuit moment.

After doing a press run for her Bravo series, Luann & Sonja: Welcome to Crappie Lake, The Real Housewives of New York City mom returned to the Hamptons on July 1 for some much-needed R&R. She kicked off the holiday weekend with friends and family in Sag Harbor, where she showed off a sizzling bikini look and her stunning home addition.

Luann de Lesseps shares a backyard update

In the July 1 video, the “Feelin Jovani” singer was seen rocking an azure blue two-piece with silver detailing on the top and bottom. The clip began with Luann standing in her Sag Harbor backyard before she took the very first jump into her newly completed swimming pool.

“Maiden voyage into the swimming pool that we finally got!” she told the camera before removing her black sunglasses. “It’s only taken four years! Here we go!”

She then did a cannonball as the person behind the camera cheered her on.

The following slide provided a closer look at Luann’s new backyard amenity, which has a spillover spa.

“Finally enjoying my pool with the family,” she said in another video clip before turning the camera to her niece’s baby bump. “And my fabulous niece is expecting.”

Luann also posted photos of her home-cooked lobster dinner and her visit to East Hampton’s Moby’s restaurant, where she snapped a photo with designer Nicole Miller and author Candace Bushnell.

“Happy [4th of July] weekend!” she captioned the post. “Nothing beats time with friends [and] family!”
