Hey dad! Kingston James McGregor Rossdale shoots Gavin Rossdale a blue-tinged grin as he watches him perform across the stage on Wednesday in Los Angeles.

Gavin was playing the Donate Life Concert Series at L.A. LIVE and brought his toddler (plus the nanny!) along for the show. Kingston, 2 ½, will be getting used to life on the road — he heads out on tour with Gavin and mom Gwen Stefani in just a few weeks!

See more photos of Kingston and brother Zuma in their recently updated family gallery, The Stefani-Rossdales.
