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.

Never a dull moment with Gwen and her boys. See more of their playground antics in the gallery below ... and after the jump.
