Zuma Nesta Rock Rossdale Pictures

Zuma Nesta Rock Rossdale, Gwen Stefani and Gavin Rossdale’s new baby boy, went to the Beverly Hills Library on Wednesday to get his picture taken for his passport. In case you’re wondering where you’ve seen Zuma before, maybe the picture below will help jog your memory. It’s Jack Jack from the Incredibles.

Daddy loves you little guy.

Zuma’s name is also a bit of a mystery, so we’ve got some theories:

There is a beach in Malibu called Zuma where Gavin supposedly had an epiphany early one morning when he realized he wanted to be a famous rockstar. Big bro Kingston is also named after a location—Kingston, Jamaica, home to Bob Marley.

Nesta: This is Bob Marley’s middle name—G&G kinda have a thing for the reggae legend, obvs. This part of I Am Legend must have really affected them.

Rock: Gavin’s band falls into this genre of music, and Gwen has an album called Rock Steady, although her more recent work would be classified as pop. However, if they used the name "Pop," that could be traced back to an ’N Sync song and that’s really not cool. Also, the whole family lives and dresses like rock stars, so it just probably seemed natural.
