With one simple caption accompanying an image posted to Instagram on Jan. 17, Gwen Stefani, 44, confirms that she’s having a baby boy.

In the photo, the bleach blonde singer for No Doubt dons a bedazzled crown, simple teal flannel and bright red lips. She labeled the image, “I was ready to hand over the crown, but I guess I am still queen of the house.” She added more direct hash tags to alleviate any confusion: “#itsaboy” and “#surroundedbyboys.”

The singer announced the sex of her child with husband Gavin Rossdale, 48, of ’90s alternative rock band Bush. They already have two sons, Kingston, 7, and Zuma, 5.

Rossdale and Stefani married in 2002, after first meeting while their bands were on tour in 1995.

Rossdale has one daughter, model Daisy Lowe, 24, from a previous relationship with singer-songwriter Pearl Lowe.

The expected due date for the family’s third son is not publicly known.
