Gwen Stefani and Gavin Rossdale welcomed a baby boy into the world today, making their oldest son Kingston, 2, a big brother!

People reports the rockers have named their newest bundle Zuma Nesta Rock Rossdale. He was born at 12:46 p.m. and weighed eight and a half pounds.

Last week, 64 percent of you said you thought Gwen was carrying a girl — looks like Gwen will remain the only lady in the family for now! Congrats to the whole band!
