Gwen and boys at the Malibu Country Mart

Kingston Rossdale has a rock star personality ... and a shaved head to match!

While spending time at the Malibu Country Mart with mom Gwen Stefani and little brother Zuma, Kingston was proud to show off his new look. We kinda liked the blue mohawk, but the 5-year-old tot is pulling off this edgy 'do, too.

Kingston is wearing Boys Space Swimtrunks by Gap (sold out) 

and Vintage Billy Joel The Stranger Tour T-Shirt. ($200.00 - only for adults). 

Gwen is carrying Kingston's Chameleons Translucent Clogs in Celery/Sea Blue by Crocs ($39.99).

Zuma is wearing Trainer Hood Logo Set by Rocket Salad (sold out online).
