Nicole Richie's Changing Looks

The 11-year-old adopted daughter of Lionel Richie looked sweet in a curly updo.

Richie made her debut on The Simple Life wearing bold colored extensions.

For her reality show's second season, Richie tried refined golden blond waves.

Richie traded in her long locks for a sleek bob with side-swept bangs.

The fashion icon filmed her final season of The Simple Life.

Richie launched her jewelry line, House of Harlow 1960, named after daughter Harlow Madden.

She gave birth to her second child with boyfriend Joel Madden, Sparrow James Midnight.

The industrious Richie launched her House of Harlow 1960 shoe line and her Winter Kate clothing collection. "I've always had lots of ideas for things I wanted to make for myself," she told InStyle.

Richie pulled her blond Bonnie and Clyde bob back into a loose half-updo.

Richie's hairstylist Andy LeCompte swept her locks into a mod ponytail for the Golden Globes.

Richie sported wispy fringe to the launch of her fragrance.

The designer went with dramatic dark shadow for the ALMA Awards.

"Nicole has the personality and look to never let the makeup wear her," said makeup artist Beau Nelson of Richie's dress-matching Golden Globes shadow. He used Elizabeth Arden's Eye Shadow Single in Sky on her lids, before defining Richie's upper and lower lash lines with Elizabeth Arden's Smoky Eyes Pencil in Midnight.

The Candidly Nicole star debuted lavender strands on Instagram in March. She told InStyle she underwent the bleaching process twice, and it took "forever."

Three months after coloring her tresses a lavender hue, Richie switched things up and went with a cerulean shade. "I was just ready for a change and I thought, once you bleach your hair, you might as well go through the colors," she told InStyle. "Because I'm going to be 33, when is this really going to happen again?"
