Gwen Stefani worried her son will be a freak

Gwen Stefani is worried her three-year-old son Kingston will be a "freak".

The No Doubt singer – who has another son, nine-month-old Zuma, with husband Gavin Rossdale – is concerned about what Kingston will be like in later life as he is so demanding.

She explained: "It's one thing when you have an infant, but when you have this two-or three-year-old going, 'Mommy, what's the deal?' It's harder. Kingston's whole thing is, 'I need, I need.' He is insane right now.

"We're just hoping for the best and that he's not going to turn out to be a freak, but we'll see."

Gwen – who is currently on tour with her recently reformed band – says becoming a wife and mother has changed her priorities, meaning she is not as willing to put the group first as she previously was.

She also revealed the band's decision to play shows without a new album to promote was not what they initially envisioned, but they were forced to after she got writer's block.

She explained to America's Elle magazine: "I might never be able to write another song. Who knows? I did try. So here we are, going on a tour without a new record.

"But, then I think, what I've gone through is major, right? I got married and had two human beings come out of my body - plus two solo albums and two clothing lines that were born during the same period.

I'm still nursing! I'm a little sucked dry. Like maybe once I sleep through the night, maybe I'll be able to write a song. That's where I'm at."
