From his ever-changing hair to his hip attire, we’re always in awe of Kingston Rossdale‘s trendsetting style.

But even we had do a double take when we spotted him in a pink tutu at a friend’s birthday party in Sherman Oaks, Calif. on June 2.

The tyke, who turned 7 on May 26, attended the princess-themed bash with mom Gwen Stefani, dad Gavin Rossdale and little brother Zuma, 4½.

And although Kingston arrived in a cool tee and cargo shorts, he had no problems throwing on the tulle skirt while enjoying the festivities.

He even gave us a peek at his missing front teeth.
