Gwen Stefani joined Instagram today (Jan. 17) and she did so in big way. The pregnant singer posted a pic of her usually gorgeous self, red lips and all, with a crown on her head, revealing the sex of her third child.

Stefani and rocker hubby Gavin Rossdale are expecting another boy!

The little guy, currently in utero, will join big brothers Kingston, 7, and Zuma, 5.

Given Stefani's impeccable style, since she is also a trendsetting fashion designer in addition to being a pop diva, many of her fans and the media were hoping she'd finally have a girl to whom she could pass along her enviable wardrobe. But such is not the case.

We're sure the singer, 44, is happy regardless. She remains the queen of the castle.

She captioned the photo as such: "I was ready to hand over the crown. but I guess I am still queen of the house. #itsaboy #surroundedbyboys."

Now that we know for sure Gwen, who looks uh-mazing and 10 years younger than her actual age, is adding another boy to the brood, we're left with one important question – what will she name her next little guy? We're sure he'll be adorbs and have a cool moniker, since Kingston and Zuma are the cutest, best-dressed little boys in L.A.
