Gwen Stefani & Gavin Rossdale Have a Boy!

It's a rock band in the making: Gwen Stefani and her rocker husband Gavin Rossdale welcomed their second child, a son, on Thursday in Los Angeles, PEOPLE has learned.

The couple named the boy Zuma Nesta Rock Rossdale, a rep for Stefani says.

Zuma joins the couple's other son Kingston, who turned 2 in May.

Stefani, 38, who is one of four children herself, has spoken openly about her hope for more children. "I'm in a race to have another," she told InStyle last year before announcing her pregnancy.

The No Doubt singer, also the designer behind the L.A.M.B and Harajuku Lovers fashion lines, told the magazine that Rossdale is "super into being a dad."

Rossdale, 42, told PEOPLE that the couple planned to follow friends' advice and get a gift for Kingston so he didn't feel left out when his new sibling arrived. "Apparently when the baby comes home, you've got to bring a really good present for Kingston," he said.
