Leakes also executive produces the show, which chronicles the preparations of her wedding to her former and future husband Gregg.
"It feels different than I thought it would," she told EW.com Wednesday about her new series.
"Although I was the first Atlanta housewife they offered a spinoff to, I never took it, because I always felt like it would be hard work," she said.
"So, when Gregg and I got married, we got engaged last year, and Bravo heard about it and asked us if we would do our wedding on television, we said, 'Yeah, we'll do a 2-hour special.' And they were like, 'No, we weren't thinking of a 2-hour special; we were thinking about a whole show about your wedding.' I said, 'Oh, OK, like a couple of episodes?' And they were like, 'No, we're talking about six episodes.' And then I thought, 'Six, that's a lot.' And they came back and said eight, and I was like, 'Oh, my God, that's a lot.' So, Gregg and I talked about it back and forth, and talked about it with our team, and we thought maybe we should do this. It is a lot of work, because I executive produce the show -- my work is doubled.
"When I say a lot of work, it's me: NeNe. I'm having to shoot three scenes a day, changing clothes three times in one day to do different scenes, so I'm just constantly working," she said. "You know, when it's your show, you got to promote it, you have to push it, you have to make this thing work. Now, when I'm on 'RHOA,' it's six of us pushing and pulling, so the work isn't as heavy a load, because they've got all the pushing and pulling. But this time, it's all about me."
