Listen to No Doubt on iHeartRadio

(Yahoo!) - Gwen Stefani may be seriously outnumbered, but she's still the queen of her castle.

The 44-year-old singer announced on Instagram Friday that she and her husband, Gavin Rossdale, are expecting another boy.

"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, who have remained mum on the pregnancy up until now, are already parents to sons Kingston, 7, and Zuma, 5. Rossdale, 48, also has a 24-year-old daughter, model Daisy Lowe, from a previous relationship.

Though we must admit we were a tad excited at the prospect of seeing the No Doubt frontwoman dress up a little girl, we're sure Gwen's new bundle of joy will have a rockin' style all his own much like his big brothers.
