He's here! Gwen Stefani welcomed her third son on Friday, Feb. 28.

The news of the baby boy's birth was confirmed by Us Weekly.

Stefani, who was stylishly dressed throughout her gestation, is already mom to sons Kingston, 7, and Zuma, 5. Those two are easily some of the best-dressed tots in Hollywood. Dad is her husband of 11 years, Bush rocker Gavin Rossdale.

Many fans hoped Stefani, 44, would have a daughter to whom she could bequeath her enviable closet. But she shared the good news that it would be another boy when she joined Instagram last month.

With four men in her nuclear family, she remains the Queen G.

The No Doubt singer had planned to expand her brood a few years ago, but claimed that "it didn't really work out." She didn't further elaborate.

Congrats to Gwen and Gavin, and to Kingston and Zuma on their baby brother.

UPDATE: The name of Gwen and Gavin's new baby has been confirmed: Apollo Bowie Flynn Rossdale.
