Gwen Stefani And Husband Wanted Third Child But "It Didn't Really Work Out"

A third child just wasn't in the cards for Gwen Stefani and husband Gavin Rossdale, even though the couple hoped to grow the family by one more.

Stefani revealed in the cover story for the October issue of Marie Claire that she sincerely wanted a sibling for her two sons, 6-year-old Kingston and 4-year-old Zuma, but things didn't go as planned.

"I really, really, really wanted one about two years ago. And it didn't really work out," Stefani said. "So. . . I feel good with what we've got. Everything works out how it should. You can't plan anything, right? You can try."

But she's plenty busy with the two boys she does have, she told the magazine.

"From the moment they wake up, they start beating on each other. I never knew they would be so physical," she said. "They're just starting to play real well together, but with a lot of fighting. They do look out for each other -- especially the little one, he really loves his older brother."

Stefani has been busy making "Push and Shove," the first studio album from No Doubt in 11 years. The album's lead single, "Settle Down," debuted over the summer and the full record is set to hit shelves Sept. 25.

She said making the album was particularly difficult as she tried to balance recording sessions with being a mother and running three clothing lines.

"I would be up all night because my second baby didn't sleep, and he had a lot of ear infections. Then I'd wake up in the morning and do my workout, which I always felt I had to do, and then meetings for my three clothing lines, and then hang out with my kids, take them to preschool, da-da-da," she said. "And then at 4 o'clock, I'd be like, 'All right, I'm out of here, I'm going to go to the studio' and try to write a record.' Sit on the couch [with my bandmates] and be like, 'Let's do this now because I'm missing time with the kids; I could be having dinner with them and putting them to bed.' It was really hard."
