Willow Smith brought some sunshine to Los Angeles. The 11-year-old “Fireball” debuted her latest look, a bright yellow dome to match her cheery mood.

She was all smiles as she and a pal held hands and strolled through The Grove shopping center on Saturday, rocking a black hat, red hoodie, and Louis Vuitton purse. See her glow below.
