Willow Smith has gone green -- with her hair.

Over the weekend, the 11-year-old Whip My Hair singer debuted her green hair via her Instagram account, with a series of new photos and inspirational quotes for her fans.

I am starting a LAGIT thingy with people around the world . . . Can share ALL of their styles . . . #uniqlook, Smith wrote in a caption for one photo.

Take Control . . ., she wrote for another.

In February, Smith shocked some of her fans when she posted new photos of her newly shaved head, fresh from a ballet class.

Three weeks later, she made hair headlines again when she dyed her shaved head bleach blonde.

Nerds Rule, she wrote on Twitter, attaching a photo of her new look with extra-large glasses.

Smith's ever-changing hairstyles and eye-popping looks have earned her great praise, with some comparing her to the always enchanting Nicki Minaj.

Late last year, Minaj was featured on Smith's song Fireball, along with a music video where the duo sported equally colorful outfits, hairstyles and dance moves.

Smith later paid tribute to Minaj by sporting a pink-ish bouffant wig in Los Angeles in January.

Thank you @nikkiminaj, you're amazing, Smith wrote, along with a photo of her Minaj-esqe hair.

Smith, daughter Will Smith and Jada Pinkett Smith, is gearing up for her debut album, Knees and Elbows, out in April. Her biggest hit to date, Whip My Hair, was released nearly two years ago, reaching as high as number two in the UK and number five on the US R&B Billboard chart.
