Gwen Stefani and husband Gavin Rossdale welcomed a baby boy on Friday, a source tells X17online. Still no word on the name, but we have a feeling the proud parents will be letting the world know sooner or later -- and given their history, it's gonna be a unique one!

Last month Gwen revealed that she was expecting a boy, and she uploaded a photo of herself wearing a crown and wrote, "I was ready to hand over the crown. But I guess I am still queen of the house. #itsaboy #surroundedbyboys."

The couple have been married for 11 years, and this is their third son; they are already parents to sons Kingston, 7, and Zuma, 5. Congrats!
