Gavin Rossdale, Gwen Stefani suit and tie Zuma grandparents Sunday

Don't mess with this one! I love how the "Cool" singer can wear a wacky outfit like that - loves the shoes, too! - and simultaneously carry around a bundle of kids' clothes under her arm. No need to sacrifice your style just because you're a mom now!

Gwen and Gavin dressed up in their Sunday best at Gwen's folks' house, but it looks like baby Zuma was the one having all the fun running around the front yard:

Energetic kid! He's almost as cute as Kingston...
