GWEN Stefani hasn’t ruled out having another child.

The It’s My Life hitmaker — who raises Kingston, three, and one-year-old Zuma with husband Gavin Rossdale — says she’s keen to add to her brood in the future.

“It could happen,” said the No Doubt star. “But who knows. I kinda have a lot on my plate right now being a mom. My three-year-old is so naughty and I have the baby as well.” Gwen recently admitted she was a bag of nerves when she had to hit the runway in front of an audience during one of her L.A.M.B. fashion shows at New York Fashion Week.

“I do get nervous right before the girls go out, and I don’t like going out there myself,” she said.“The catwalk is just a different place to the stage. I find it so much more scary. Everyone is there and can be critical about your work. I’m proud of my work but it’s a daunting place to be.”
