Gavin & The Boys Go On a Mother's Day Mission for Gwen

Rocker Gavin Rossdale received some help from a nanny as he and his two boys Kingston and Zuma Rossdale hit a Studio City, Calif. grocery store yesterday for Mother's Day supplies for his lovely wife Gwen Stefani! The boys relaxed in the stroller for much of the shopping spree, but they certainly picked out some great presents for mom!

OK! GALLERY: GAVIN & GWEN SHOP SEPARATELY, DON'T DROP

The boys grabbed some flowers, a Mother's Day heart balloon and a bunch of groceries to bring home to mom!

Wonder if they were making breakfast in bed?
