Gwen Stefani proves she ain't no Hollaback Girl as her Harajuku Mini line dominates the spotlight at Target with its debut in the department store on Sunday.

Stefani held her launch party at Jim Henson Studios in L.A. and wore a psychedelic printed pantsuit from her L.A.M.B. line, an elaborate gold collar necklace and sky-high platforms. Her hair was twisted up in a geisha-inspired bun, and she had on her classic red lipstick.

The pop singer brought her two sons, Zuma and Kingston, to walk the catwalk with her in some of the Harajuku Mini designs.

Hollywood's hottest A-list moms like Ali Larter, Maya Rudolph, Brooke Burke, Selma Blair and Paula Patton hit the bull's-eye red carpet on Nov. 13 to get a glimpse of Stefani's children's clothing line, reports the Daily Mail.

They posed for photographers under a tower of balloons. Many of the attendees donned causal, stylish attire like black boots, leather jackets and chunky knits.

The Japanese street style-influenced line features plaid and leopard print dresses, cool graphic t-shirts, printed hoodies, sweater vests and corduroy pants. All clothes are grouped into three adorable groups -- Animal Collective, Nerd Rock and Girlie Glam. Prices range from $3.99 to $59.99, totally affordable options for everyday moms.

 Harajuku Mini is a dream come true, Stefani said in a statement in July announcing the collaboration.

I've always wanted to do a cool children's fashion line inspired by the super-cute and playful kids' clothing you find in Japan, she said.

The whole idea is about being creative, expressing your own individuality and having fun getting dressed.

Target has given me the creative freedom to design kid's clothing that is different than most anything you usually see out there with great quality, attention to detail and, most of all, available at amazing prices, she said.

The goal of the department store was to introduce a line for the children's wear collection that displayed a break from the ordinary. They wanted to add something distinctive and modern.

Stefani, of course, is the ideal contender for such a task. Her personal style is known for its bold, unique flair. 

The 42-year-old mother introduced her first Harajuku line, Harajuku Lovers, back in 2005. It was named after the quirky, fashion-forward region Harajuku Station in Tokyo, Japan, according to the Daily Mail. The line consists of bags, laptop cases and fragrances. 

Many have been citing Harajuku Mini as the biggest, most anticipated Target-designer collaboration since Missoni back in September.
