Gwen and Baby Kingston Rock Stockholm

Little Kingston James Rossdale, 16 months, receives a little toddling assistance from rockmom Gwen Stefani in Stockholm. Hollaback, ma!

Gwen and babe took this little escape from her Sweet Escape tour, which winds through Helsinki and on to Copenhagen for tonight -- she'll wind it up in Las Vegas and San Diego later this month.

This is the best dressed baby in Hollywood -- and probably Helsinki too.
