LuAnn De Lesseps' marriage may not have lasted, but according to the longtime reality star, their wedding was the highlight of The Real Housewives of New York City season nine.

During the third part of the three-part reunion special on Wednesday night, host Andy Cohen asked all of the women about the ups and downs of season nine.

“As you can imagine, the highlight of the season for me was getting married,” De Lesseps said, according to a report from Radar Online on August 31.

As for the downside of the season, De Lesseps added, "All of the talk about [my husband] Tom [D’Agostino], because I love him, and so it was tough, but I got through it, and I appreciate all of you being concerned about me and looking out for me and having my back.”

Within just three weeks of the reunion’s filming, De Lesseps confirmed plans to divorce husband Tom D'Agostino to her fans and followers on Twitter.

“It’s with great sadness that Tom & I agreed to divorce. We care for each other very much, hope you respect our privacy during this sad time!” she wrote on August 3.

During her upcoming divorce tell-all with Andy Cohen, De Lesseps will go into more detail about the end of her marriage.

“It was like the week before the reunion basically, and Tom went out and he called an old girlfriend and they met up with a group of people,” De Lesseps explained to Cohen. “And I didn’t know about it until I found out about it the next day in the press.”

“That for me was the final straw, I can’t do this anymore,” she added.
