Gwen Stefani looked to an unusual source when deciding what to call her new son - she named the baby ZUMA after her No Doubt bandmate suggested the moniker.
It was reported that Stefani and Gavin Rossdale named their seven-month old tot after the couple's favourite California beach.
But the singer has revealed her second son's unusual name actually came from the band's guitarist Tom Dumont, whose wife Mieke rejected it for their two sons, Ace and Rio.
Stefani tells radio show Mojo in the Morning, "I kind of stole it from him. I didn't steal it, I mean his wife didn't want it. It was just one of those things that just happened. I just wanted Zuma to have a little bit of a quirky name."
The couple also has a two year old son, Kingston.
