LuAnn de Lesseps says her wedding will be an elaborate three-day affair.

The 51-year-old "The Real Housewives of New York City" star spilled details about her upcoming nuptials to Tom D'Agostino, Jr., while appearing on an episode of "The Steve Harvey Show" set to air Monday.

"[It's a] traditional wedding, [then] it's his 50th birthday and [then] it's New Year's Eve," de Lesseps revealed, according to E! News. "It's a destination wedding in Palm Beach. It's a three day affair. "

"I'm wearing three dresses. I wanted to wear, like, something traditional to walk down the aisle, because Tom has never been married, so I wanted to be his bride," she added. "Then for his birthday, I was maybe going to sing a little something for him. And then for New Year's Eve, I wanted to wear something really blingy and fun."

De Lesseps was previously married to Alexandre de Lesseps and shares two children, son Noel and daughter Victoria, with her ex-husband.

She confirmed in September that her engagement to D'Agostino is still on despite him kissing another woman.

"Yes, we did hit a little bump in the road," the star told Harvey. "I think when those things happens, it's a real test of people loving each other and getting past things that happen. I think that if you can't forgive someone you love, who can you forgive?"

"It's made us stronger than ever. I knew then and I know now that we do love each other. And that's the most important thing, so we're getting married," she said.
