Inside Luann de Lesseps’ Miami Bachelorette Party with Real Housewives Alums

It was girls’ night out on Friday night as soon-to-be-married Luann de Lesseps and 15 of her friends partied at the 51-year-old Real Housewives of New York star’s bachelorette party in Miami!

The event, thrown by Real Housewives of Miami alum Marysol Patton, was held at the famed Peruvian hot spot Coya — where the tight-knit ladies enjoyed a three-course sit-down dinner and an open bar cocktail reception featuring the club’s signature Pisco sour cocktails, a source close to de Lesseps tells PEOPLE.

De Lesseps was all smiles, wearing a sparkly tiara that said “Bachelorette,” a fur shrug and embellished T-shirt that said “Mrs. D’Agostino” — in honor of her fiancé Tom D’Agostino, Jr.

He proposed to her in February with an eight-carat yellow-diamond ring after a few weeks of dating. Their relationship was the fodder for much drama on this season of Bravo’s hit reality show, as D’Agostino, Jr. allegedly had a “friends with benefits” relationship with Housewife Sonja Morgan —and had previously dated Housewife Ramona Singer.

Neither Morgan nor Singer were in attendance at the Miami party. Instead, the night was filled with alums of the Real Housewives franchise, including RHONY’s Jill Zarin and RHOM’s Adriana de Moura and Alexia Echevarria.

All the ladies shared shots of the fun on their Instagram page. It’s the first time Echevarria has been seen out since her husband, Herman, was found dead in his apartment on Sept. 26.

After the “sumptuous” meal — which included a sparking dessert — the insider told PEOPLE the live music started.

“Everyone was up and dancing,” the source continued. ” The party ran about 5 hours and then everyone went off to some club to continue dancing.”

This isn’t the first wedding event de Lesseps has been to in the past few weeks. On Sept. 29, her friends threw her a lavish bridal shower in New York.

The happy couple will wed on New Year’s Eve in Palm Beach, Florida — and will be expecting about 250 guests (including Medley, Morgan and former Housewife Jules Wainstein).

“I’m so in love,” de Lesseps previously gushed to PEOPLE. “I’m most excited to celebrate – to celebrate our life together and to have all our friends together.”

She was previously married to Count Alexandre de Lesseps, 66, from 1993 to 2009. The pair share two children, son Noel and daughter Victoria.

“I’m excited to walk down the aisle,” de Lesseps told PEOPLE. “I’ve never done it – I eloped. So I never have been married in a traditional way so I’m excited to be a bride. That’s why I’m wearing a veil.”

Oh, and de Lesseps will wear three dresses.

“I’ve got three things to celebrate: it’s our wedding, it’s Tom’s birthday and it’s New Year’s Eve,” she shared with PEOPLE. “So I’m feeling like I’m gonna go very traditional bride, and then party dress for Tom, and then glitz and glamour for New Year’s Eve.”

Of the bridal fashion moment, she joked, “Why wear one when you can wear three?”
