Kelly Osbourne's Changing Looks

She flaunted an asymmetrical blunt bob courtesy of Brooke Dulien. "I've worked with her since I was 15 and I don't want to go anywhere without her!" Osbourne has said of the hairstylist. "No one knows me better than she does."

For the Creative Arts Emmy Awards, she topped her simple crop with a bright faux orchid and matching fuchsia lipstick.

She punked out for the Nickelodeon Kids' Choice Awards with a bleached Mohawk.

For a PlayStation launch, she added a saucy twist to her short blond cut with a tilted fedora.

Osbourne hit the MTV Movie Awards with little-girl-gone-wild look: teased pigtails and baby blue shadow.

She went pitch black for the MTV Europe Music Awards, finishing the alt-chic look with a sweep of emerald shadow and bright red lipstick.

Osbourne chose barely-there makeup (and a Bettie Page wig!) for the N.Y.C. opening of The Merchant of Venice.

She played up her signature red lips with apricot locks for a Cali fundraiser.

Channeling her softer side, the Brit matched a faux-hair headband to her then-blond crop.

Osbourne chopped her brunet strands into a sleek, mod pixie.

"I know it's lavender, but having my hair this color makes me feel like me again!" she tweeted of her pastel hue.

Osbourne showed off platinum blond tresses (and a new slim figure!) at the Fendi Boutique opening in L.A.

For Elton John's Oscars viewing party, the Fashion Police host paired a beehive bouffant with equally dramatic fuchsia lipstick.

Osbourne walked the red carpet at the Golden Globes sporting lavender gray locks. "I think that I have an addiction to dying my hair, because I always like it to be different," she told People of the new shade. "I don't like being compared to other people."

The star opts for Old Hollywood waves to complement her lilac 'do.

Osbourne pumps up the edge with a mohawk.

Stepping out at the Annual NYX FACE Awards in Los Angeles, Osbourne was seen rocking her usual lilac-colored locks with bold lashes and a nude lip.
