Nicole Richie is bringing her humor and sass back to reality TV with her own show, Candidly Nicole.

And before its premiere tonight, the mom of two and wife of Joel Madden called in to On Air with Ryan Seacrest to chat about it, as well as other topics, like her hair color.

So why does she have blue hair? “My daughter picks out my hair colors and she’s having fun with it and it makes her happy, so I just thought, ‘Why not? It’s temporary.’ She likes it. And anything that makes her happy, makes me happy. It’s summer.”

And Nicole’s laid-back and fun approach to her hair color is much like her reality show, which first began as a web series.

“We just had so much fun doing it because I wanted to create a space where I was still learning and exploring, but also having fun,” she explains. “We cover different topics from online dating to millennials to being your own boss. But we discover and explore it in such silly ways. You’re still coming home with some take-away, but also just laughing and having so much fun.”

Speaking of online dating, Ryan of course had to ask Nicole if it was true that she played matchmaker for her brother-in-law Benji Madden and her good friend Cameron Diaz.

“Sarcasm and print don’t always go hand in hand,” says Nicole about her answer to the same question on Bravo’s Watch What Happens Live earlier this week. “[I'm] kidding, [I'm] not being serious. I try not be accountable for any of my words.”

But one thing she is not joking about: Whether or not she and Joel will have more children. “We didn’t plan the first two, so it’s not really up to us, I guess. We’re just a go-with-the-flow … we’ve never done anything in traditional order.”

Candidly Nicole premieres tonight on VH1 at 10/9c!
