Which Real Housewife of New York Will Be a Bridesmaid in Luann de Lesseps' Wedding?

When it comes to planning her upcoming wedding to Thomas D'Agostino Jr., Luann de Lesseps is going big or going home. Weeks after getting engaged to the businessman, the Real Housewives of New York bride-to-be is already plotting every detail around her nuptials, which will likely take place in Palm Beach, Florida. "We're looking for locations," she told Us Weekly, adding that they're eyeing December 31 as a date. "Tom is going to be 50 on New Year's Eve and he's never been married so what better time to get married than on New Year's Eve and on your birthday? I want a big blowout wedding!" she explained. "We're both Catholics. We want to get married in church with priests, the whole nine yards. Lunches and dinners and parties on yachts.” Luann also confirmed that Dorinda Medley has earned a spot as one of her bridesmaids after playing matchmaker for the couple.

Luann and Thomas started dating in late November and were engaged on February 5. Luann says she knew "after a week" that she wanted to walk down the aisle with him. "Well, you know when you know," she told Us Weekly. "I'm very fast. You either jump on the train or you miss it." And, yes, by taking on the D'Agostino name, Luann will be giving up her Countess title. But, she's just fine with that. "I've been carrying around that title for a long time. I have no problem with losing it," she said. "So Tom says to me, 'You're going to marry a commoner, how do you feel about that?' I go, 'Honey I will marry a commoner any day.' There's nothing common about Tom and I found my match, which is so rare. I'm lucky I found it the first time, nevermind a second time."

As for Thomas' previous flings with Sonja Morgan and Romana Singer, Luann isn't too worried about his life before they were together. "I think he had a little date. They're attractive women. He was a single guy. I was single. I was dating. It's a very small circle in New York. Whatever happened before Lu doesn't count," she said. "I am the one walking down the aisle. Not them. He took them out for dinner; there was no big romance there."
