Every four-year-old boy should have a bleached mohawk and be treated to a mani-pedi in Beverly Hills, right?

Only if you are Gwen Stefani's son.

The pop star's oldest child, Kingston, was spotted this weekend with a bleached blonde mohawk hairstyle complete with a shaved head on both sides. He also rocked brightly colored fingernails and toenails in a myriad of shades as he walked out of the nail salon in flip-flops so as not to disturb his freshly-painted toes.

Rocker-mom Stefani was also spotted at the salon getting a touch-up on her black nail polish before the duo met up with Kingston's little brother, Zuma, and their father, Gavin Rossdale, for a family outing to "Yo Gabba Gabba! Live!" in Los Angeles.

Once there, the child fashion icon sported a black leather jacket to complement his skinny gray jeans and colorful slip-on sneakers.

What do you think of Kingston's rock-star style? Appropriate for a young tot or not?
