Currently in the midst of a remodel, "there are a lot of green aspects to my house that I'm rebuilding," says Shannen Doherty. "We have solar panels, and the water that heats the floor. We're putting in all native California plants. But I might have a few roses. It won't be all cacti," says the former "Beverly Hills 90210" star, whose latest project is "Shannen Says," a WE tv reality series premiering April 3 that chronicles the preparations leading up to her wedding. Doherty married photographer Kurt Iswarienko on Oct. 15, 2011, her third wedding. Doherty admits to having reservations and hesitating before signing up for the eight episode series.

"Why would we do this? I'm an actor, he's a photographer, why are we interesting? What are we bringing to the table?" she considered, before ultimately deciding, "We wanted to work together and we put a team together that made us feel confident about doing the show. And it was a great excuse for me to hang out with my best friend for seven weeks straight. I think we're both happy that we did it, at the end of the day."

There were, however, some ground rules. "We said that no matter what, we wanted the show to be completely honest, true and authentic. We did not want one of those shows that people watch and they roll their eyes at and go, 'Yeah, right, like, that happened. That's a setup' — we don't want that. So when there was conflict about schedules or Kurt leaving for a job three weeks before the wedding and I was flipping out about it, you see it."

The couple met almost four years ago, at a photo shoot. "It was love at first sight," says Doherty. "The world sort of stood still for a second. He just instantly felt like my best friend. And I thought, 'this one is going to stick.'"

Although she's older and wiser than she was during her "90210" days, when she was a tabloid fixture for her wild behavior, she's also a realist. "You get older and you don't want to be thought of as this 19-year-old brat. That doesn't mean that I did the show with it in my head that I should change people's perceptions. Haters are still going to hate me. It's not my job to make them feel better about themselves, or like me more," Doherty says.

She's considering a second season of the show, which might cover her efforts to become a country music star and/or open a steakhouse restaurant. "Right now, Kurt and I are both happy with the eight episodes as a documentary of what happens when you decide to get married, and the things all of us face. Men and women are so incredibly different," she muses. "It's about how you find some middle ground to work through problems."
