Nicki Minaj's Changing Looks

The Pink Friday rapper hit BET's Rip the Runway in a restrained (for her) black wig with pink highlights.

She visited 106 & Park in a blond Cleopatra bob streaked with green. Matching eye shadow and neon pink lipstick finished the colorful look.

Another wig, another wash of color-a hot pink hue gave her MTV Video Music Awards 'do a cartoonish feel.

For the Hip Hop Awards, Minaj went ladylike with a platinum blond wig and lilac lipstick.

Ombre, Minaj style. She sported green-dipped ends at the American Music Awards.

Minaj celebrated her MAC Pink Friday lipstick wearing the frosty shade-and rainbow-hued locks.

She performed at the VH1 Divas Salute the Troops concert with pink-tinted sculptural curls.

"Yes, this is all my hair," Minaj joked of her Grammys Bride of Frankenstein bouffant. "At night, if I press a certain button, my hair grows. First of all, it grows up, and I press another button and activate the color on it."

Back to basics at the Billboard Awards. Minaj matched her lipstick to her hot pink curls.

For the BET Awards, the rapper chose a demure '70s-inspired crop, voluminous lashes and fuchsia lips.

Minaj covered up her signature lipstick with a Shojono Tomo mask at the MTV Video Music Awards. She balanced out the unexpected accessory with a towering pink and yellow updo and turquoise-lined eyes.

For a festival appearance, Minaj got girly with curly pigtails.

Half blue and half blond for the American Music Awards nominations.

Minaj honored Versace's bold prints at the launch of the label's H&M collaboration with a palm-frond accented mass of green curls.

Pretty in pink for the American Music Awards.

Minaj went for waist-length platinum waves at Billboard's Women in Music gathering.

For the Super Bowl, Minaj had a very special stylist. "Madonna was the first person in history who was able to make me change my wig," Minaj told Ryan Seacrest. "I went through four color changes on my wig for the Super Bowl. We got the platinum blond and she smiled. Once she smiled, I was like, 'Thank you, Jesus!' I couldn't take it anymore." The Material Girl also chose the rapper's bold red lip color.

"My MAC Viva Glam lipstick hits counters today Barbz!" Minaj wrote her fans on Twitter prior to the launch of the bold pink shade. 100% of the proceeds from the lipstick go to the MAC AIDS fund.

Minaj chose a tumble of blond curls for the American Music Awards.

The rapper arrived at a sneak peak of her Kmart collection at Fig & Olive Melrose Place in Hollywood wearing a white corset dress and blunt, blonde bangs. 

Minaj simplified her look for the Billboard Music Awards and wore her hair in beautiful, soft curls with au naturel makeup. 

Minaj stunned at the MTV Video Music Awards in a metallic-colored, golden gown and jet black 'do with a bold cateye to finish the look.

Minaj gathered her braided locks in a glam high ponytail, opting for dramatic lashes, gold eye shadow, and a bubblegum pink lip. 

The Pinkprint singer wore her platinum locks parted down the middle, adopting her signature pink lip and high-wattage eyelashes.
