After teasing fans with a photoshopped image of herself sporting lilac locks, the fashionista took the plunge and decided to try out the new look. Perhaps she was convinced after fans tweeted their excitement at the purple style.
Her new style was confirmed by Kelly Osbourne. The star, who is famous for her violet hair, shared a snap of the pair posing together. "Guess took the bet & dyed there hair MY color @nicolerichie [sic]," she captioned the selfie.
Nicole also posted a picture of her purple hair tied back into a sleek bun. She is posing next to her husband Joel Madden.
It's not the first time Nicole has experimented with her hair. Last year, she stepped out for the Met Ball sporting completely white tresses. It was in honour of the theme of the event, punk.
Demi Lovato has also unveiled a new, drastic hair transformation. The singer, who dyed her hair hot pink back in January before embarking on her Neon Lights tour, shaved off one side of her head.
She took to Instagram to share several snaps of the new 'do, writing: "So… This happened… Oops. #NEONLIGHTSHOUR."
Demi’s edgy new look shows a portion of the side of her head buzzed, with the rest of her hair still long, flowing and hot pink.
