Stefani's middle son, Zuma, was born on 21 Aug., 2008. According to People, his name is said to be inspired by Zuma Beach in Malibu, California, and one of his middle names, Rock, could be a nod to No Doubt's 2001 album "Rock Steady" — or maybe it's just to honour his two rockstar parents.
On Zuma's 14th birthday, Rossdale shared a photo of his son on Instagram, writing: "HAPPY BIRTHDAY ZUMA - my sweetest boy you are the shine of my sun.i love everything about you.a magical boy indeed. layers on layers.so happy you're mine. you've even made me fall in like with baseball YOU HAVE AN ARM OF GOLD. and you can hit the life out of a ball that flies at 80 mph. you're amazing. we are gonna celebrate hard. because that's how we roll."
