"I am telling you, I was so excited to find the man, I didn't even think about planning," newly engaged Nash tells PEOPLE.
Nash, 40, is going to get a little help with that planning: She announced Monday that the TLC network will air a two-hour special documenting her late-May wedding to Tucker, an electrical engineer, as well as the steps leading up to their wedding day, including finding a dress and the perfect venue.
"I am a woman who does not have the bride gene," says Nash. "No bridezilla here! I haven't been planning a wedding since I was three. I have to go to the experts to say, 'What am I supposed to do here?' And me and my mother watch Say Yes to the Dress religiously. So I'm really looking forward to it."
The comedienne and actress also wanted to give something back to fans. "I said to Jay, 'I would like to share this experience with them,' " says Nash. "I want them to know at the end of the day [that] love is possible a second – sometimes even a third – time around. You can get another chance."
Happy to Have a Do-OverNash's first marriage lasted 16 years, ending in 2007. Thinking back to that ceremony, Nash says, "it was such a fiasco. I hadn't been to a wedding before, so when I went to get my dress, I had nothing to compare it to. I didn't know I bought a dress that's a quinceaçera gown."
At the reception, "my decorations were metal folding chairs and signs that were painted in marker and done in calligraphy," she says. "A Styrofoam heart in the middle of the table? It was just a mess. So I am happy to get a do-over and ask for help."
Joining her will be a wedding party featuring bridesmaids Sherri Shepherd from The View, The Game's Wendy Raquel Robinson, and actress Sheryl Lee Ralph as the matron of honor.
"What I do know," Nash says, alluding to the royal wedding happening a month before her own, "is that when Kate [Middleton] and her guy get married, they're going to have so much help to pull it off. Here's what I think we'll have in common: We're both beautiful brides. I think the grooms will be awfully gorgeous. I think our families will be pleased. And that's where it stops."
