Gavin Rossdale Zuma Teenage Mutant Ninja Turtles costume Gwen Stefani

How cute!!

On Friday, Gavin Rossdale and his boy Zoom were out and about in Los Angeles while his adorable son dressed as a Teenage Mutant Ninja Turtle. Is it Halloween already?

The 47-year-old Bush frontman decided to help his wife Gwen Stefani with the parenting load as she spent the day with their other son Kingston.

What a dutiful husband!
