Gwen Stefani feels 'guilty' being a working mother

She continues, "It starts getting so serious, and you're like, 'Aaaaaaah!' And to do all that while sustaining this insane childhood of my own. ... I've never had to grow up in a way. When you think about it, [No Doubt was] in college together, and then we made our first record, and then we just took off and stayed in this bubble. Time kind of stops when you're in a band. It's this suspended childhood, and it's really awesome, that part of it. But then when you have a family of your own, it forces you to go into the adult world a little bit more."

Though she and Rossdale recently celebrated their 10th wedding anniversary, the "Looking Hot" singer admits they've hit a few speed bumps along the way. "You have to work at it. But, actually, it's fun to get to this point. Because you learn so much about somebody. It's like these wars that go on and then you kind of get through it to the other side, and it's like, 'Wow,'" she tells Vogue. "And obviously, you get stronger. And then having kids takes the whole relationship to another place. It is the ultimate collaboration. Both of us have such strong opinions about how it should be, and it's really fun to do it together."
