Gwen Stefani has revealed she and husband Gavin Rossdale are expecting another baby boy.

The couple, who have been together for 16 years and married for 11, already have two sons, Kingston James McGregor, seven, and Zuma Nesta Rock, five.

Gwen announced the news on her Instagram account on Friday by posting a picture of herself wearing a crown along with the caption “I was ready to hand over the crown. but I guess I am still queen of the house. #itsaboy #surroundedbyboys.”

The No Doubt front woman revealed that she wanted another child a few years ago but it just didn’t happen at the time.

“I really, really, really wanted one about two years ago. And it didn't really work out.

“I feel good with what we've got. Everything works out how it should. You can't plan anything, right? You can try.”
