The Real Housewives of New Jersey star Danielle Staub is engaged to Oliver Maier, who says he's a duke

Another Housewife is apparently about to receive a title.

On Thursday, PEOPLE exclusively revealed that The Real Housewives of New Jersey star Danielle Staub is engaged to Oliver Maier, who told PEOPLE that he is the Duke of Provence.

Maier said his family owns 15 vineyards in the South of France as well as two castles, and that their marriage would mean that Staub, 56, would become a duchess.

But Staub is hardly the first Housewife to have a connection to royalty. Here are the other Housewives who have:

Carole Radziwill is a princess by marriage.

Radziwill, the Real Housewives of New York City alumna, was married to Prince Anthony Radziwill before he died from cancer in 1999.

Anthony, the nephew of Jackie Kennedy, was the son of Kennedy’s sister Lee Radziwill and Prince Stanislaw Albrecht Radziwill. His full title was His Serene Highness, Prince Anthony Stanislaw Albert Radziwill.

In 2017, Radziwill, 55, ran the New York City Marathon in honor of her late husband.

“People always told me what a hero Anthony was because he battled cancer. I used to hate that — I didn’t want him to have to battle cancer. And then it turns out, he was a hero after all. Because he had run that New York City marathon. I finally feel like I’m going to honor him in the way that I should have when he used to talk incessantly about running,” she said at the time.

Luann de Lesseps is a countess by marriage.

De Lesseps, often referred to as “the Countess,” married her first husband, European aristocrat Count Alexandre de Lesseps, in 1993 after only two weeks of dating.

But two children and 17 years of marriage later, the two called it quits in 2009.

Having been privately separated for three months, the Real Housewives of New York City star, 53, said she learned the divorce was moving forward when her ex-husband sent her a shocking email: “It said that he had met someone,” she recalled to PEOPLE in 2009, “and they were serious.”

“I was devastated,” she said. “I knew that we were kind of separating, but I was hoping that things were going to work out.”

Technically, she renounced her title upon her second marriage, to Tom D’Agostino Jr. (they split after just seven months.) But she still uses the moniker for her wildly popular cabaret show.

Sonja Morgan dated a royal.

Morgan, 55, once claimed that she dated Prince Albert of Monaco during an episode of The Real Housewives of New York City.

According to Bravo’s Daily Dish, she told Bethenny Frankel in season 9, “I used to wear this with Prince Albert when we were dating in Monaco. Can you believe this? It has a skirt. I must have left the skirt at Albert’s.”

Bethenny Frankel knew Duchess Meghan’s ex.

Frankel, 48, once joked that she had dated Meghan Markle‘s ex-husband.

During an interview on Australian radio program Kyle and Jackie O in April 2018, Frankel said she “kind of” went on a date with Markle’s ex, Hollywood producer Trevor Engelson

“We were supposed to go out and we ended up seeing each other one time and he’d been texting me, he’s a producer in LA,” she continued, adding that at the time he told her “he was married to this girl named Meghan Markle from the TV show Suits.”

While she initially didn’t think much of the news, after she heard about Markle’s engagement to Prince Harry, she remembered telling Enelson, “Holy s—, your ex is going to be a princess. Is that crazy?”

But even though Frankel said the pair “kind of” went on a date once, she also said they “haven’t hooked up,” and she wasn’t sure she saw the possibility of a romance blossoming between them.
