Kingston Rossdale Turns 4!

Kingston, who turned 4 on May 26, puts a modern spin on the early '90s style with a colorful plaid button-down, beaded necklace, black tee, black jeans and a rugged pair of Harley Davidson boots on Mother's Day.

Watch out, Zoolander! In a striped blazer, multi-colored scarf, cream pants and navy-and-white saddle shoes, Kingston gets all dressed up – and strikes a fierce pose – for a cousin's christening on April 18 in Los Angeles.

Just a month shy of his fourth birthday, Kingston takes the urchin look from street to chic in a plaid tunic, anchor-print tee, cropped trousers, red-and-white striped socks and brown work boots while hanging out in Beverly Hills.

What's the best topper for a rabbit romper? A band jacket by Stella McCartney for GapKids, of course! Kingston completed his Easter outfit with a straw bowler hat, saddle shoes and cute duck plush toy.

While enjoying some sun in St. Bart's with dad Gavin Rossdale, the 3½-year-old sported a pair of neon yellow Wayfarers by Ray Ban Junior with a hip rocker tee and plaid shorts.

With his toy dinosaur in tow, Kingston braves the chilly London weather in a red Appaman puffer coat, a patchwork denim jacket, cropped tweed pants and black motorcycle boots in December.

Who's afraid of mixed prints? Not Kingston! For a walk with mom Gwen Stefani in London on Dec. 18, the stylish tyke bundled up in a patterned wool sweater vest, plaid shirt, patchwork jeans and black motorcycle boots.

To show off some country spirit for dad Gavin Rossdale's hometown, Kingston rocked a Mohawk Union Jack knit hat while vacationing in London last winter.

On the way to a playdate in Beverly Hills on Nov. 15, Kingston, 3, makes a run for it in a cool message T-shirt, gray tweed knickers and his fave Harley Davidson motorcycle boots.

For to Mr. Bones Pumpkin Patch in West Hollywood on Oct. 27, the 3-year-old channels a '50s greaser in a black biker jacket, Lightening McQueen pit crew costume and brown motorcycle boots.

From his peasant tunic top to his fringed Minnetonka boots, Kingston looks hippie-chic while stepping out with the family in West Hollywood on Oct. 11.

Mom Gwen Stefani isn't the only fashion plate in the family: Kingston pulled out all the stops – highlighted Mohawk, army jacket, skinny jeans, Creative Recreation sneakers and yellow nail polish – for the presentation of L.A.M.B.'s spring 2010 line at N.Y.C.'s Milk Studios on Sept. 10.

A week before turning 3, Kingston goes from cutesy to totally rad after getting a brand new do, which he debuted at LAX.
