ET sat down with the 51-year-old reality star in an exclusive interview at her home in the Hamptons in August, where she revealed just how excited she was to tie the knot, even after she discovered that D'Agostino had kissed another woman at a hotel bar just days before proposing.

"We love each other," she shared. "I always say if you can't forgive the people you love, then who can you forgive? ... I'm not going to let a silly kiss ruin the rest of our lives."

"I think it was a silly move and something that he feels really terrible about, and that meant really nothing to him," she said, adding that she was looking forward to her nuptials on New Year's Eve, which also happened to be D'Agostino's 50th birthday.

In April, de Lesseps told ET that she was going above and beyond in the dress department for her big day.

"You know what, it's threefold. It's Tom's birthday, he's going to be 50, it's our wedding, and it's New Year's Eve, so I feel like I should change it up, so I'm going to do three different dresses," she revealed. " Why not? For my big night, why not have three different dresses?"
