Gwen Stefani and Gavin Rossdale are expecting another boy.

The couple already have two sons – Kingston James McGregor, seven, and Zuma Nesta Rock, five.

Gwen announced the news on Friday by posting a picture of herself wearing a gold crown on Instagram.

“I was ready to hand over the crown. but I guess I am still queen of the house. #itsaboy #surroundedbyboys,” she wrote.

Gwen and Gavin have been together for 16 years and married for 11. The singer revealed she really wanted a third child a couple of years ago, but it didn’t happen at the time.

“I really, really, really wanted one about two years ago. And it didn’t really work out,” she told US Marie Claire in 2012. “So… I feel good with what we’ve got. Everything works out how it should. You can’t plan anything, right? You can try.”

The No Doubt singer has explained how difficult it can be to juggle motherhood, her band and also being a fashion designer.

But she admits it’s a fun journey and her family means the world to her.

“It’s super fun being a mum, but it’s not what you think it’s going to be… At first, your life is totally the same… And as they grow older, it really does start to change your life,” she told US Vogue.

“Like, Oh, my God, they have school, they have to get through first grade, they have to learn to read. It starts getting so serious, and you’re like, Aaaaaaah!”
