Gene Simmons and Shannon Tweed's Kids Dish on Their Parents' Wedding and Finally Becoming a Family -- Exclusive Video

Tonight, viewers will be treated to one of rock's rarest moments. No, it's not a remaining-Beatle reunion -- it's the marriage of Gene Simmons and Shannon Tweed. After nearly 30 years of dating, they are set to tie the knot on the season finale of their hit reality series, 'Gene Simmons Family Jewels.' The couple's two children, Nick and Sophie, are both featured singing in the wedding and spoke to Spinner about their roles in the festivities.

What did this wedding mean to your family?

Nick: For me, it meant that my father chose our family, definitively, over everything else: What he's said over the years, what's expected of him in his line of work, etc.

Sophie: It meant we finally were a family. There were the Tweeds and the Simmons', but now there are the Tweed-Simmons'. As long as that last name is, it feels 10 times better.

What did it mean to sing at the wedding?

Sophie: It meant the world. Growing up thinking love is marriage and seeing my parents not married was pretty confusing. Now, I know it isn't necessarily that, but it still feels amazing to know that's it's officially "forever."

You did a nice job singing standards at the wedding. Any chance of an album from either of you?

Sophie: I haven't given any thought to singing really. My brother and I are performing for a few days at the River Rock Hotel and Casino in Vancouver at the end of November and I occasionally sing at the W Hotel Hollywood on Sundays, but it's all in good fun. I'm not signed. My majors at school are actually Computer Engineering and Religious Studies. So random.

Nick: I've been in and out of bands since high school, for fun, and we've both had offers because of the TV show. I've never taken the offers. I don't want to do it unless I feel the music is actually good enough. I think I've found the right group of guys just recently, so if the material we produce is good enough to stand on its own, then yeah, maybe I will. But I'm not just going to hop in the recording studio because we have a TV show, to take advantage of publicity or any small celebrity I've gained because of my father. I want to do it right if I do it, regardless of media attention. While I'm grateful for the opportunity I've been presented with the show, I'm going to take my time with it and try to ignore it.

So you won't do the obvious thing.

Nick: If I do an album, it's not going to be "Nick Simmons" or "Nick Simmons and the Whatevers," which would probably be the business-smart thing to do, to capitalize on the show. I'm not looking for that, and I'm not looking for a backup band. I have some talented musicians that have come forward and I want them to be an equal part of it. The band will have a name of its own, and I will merely be a member. I'd rather have the group sink on its own merits rather than swim because of my last name or a reality show.

For now, though Soph and I have been singing regularly and for fun at this place called the Sayers Club on Hollywood Blvd, and that has opened up some doors. We've taken up an offer to do some blues/jazz/classic standards at two shows in Canada on Nov. 24 and 25, with the house band at the River Rock Casino and Hotel. Real old fashioned stuff: Sinatra, Dino, Sammy, Ray Charles, Bobby Darin, Etta James, etc. It's going to be a lot of fun.
