Billie Eilish has gone blonde. "Pinch me," the<em> Bad Guy</em> singer, 19, captioned an Instagram post, which debuted her new blonde haircut on Wednesday. Shoulder-length with an angel-wing fringe, it is a return to Eilish's natural blonde hair colour. The new style is a departure from the black locks with neon green roots that have become her trademark style in the last year. She had her green and black hair on Sunday at the Grammy Awards. <strong>Click through the gallery above to see the many hair colours of Billie Eilish.</strong> In December 2020, an Instagram user commented on a photo of her hair saying that "grass head needs a new colour". Eilish responded to the troll saying, "It's called not being depressed anymore pls just be happy for me." She also wrote: "This is the longest I've had the same hair colour since I was 13 and that's on mental stability and growth, leave me alone." "I’m in love, this is amazing, she can honestly rock any colour or any haircut," one admiring fan commented on Instagram. Another added: "Oh my God, you are so stunning it’s unreal." She was also compared to Charlize Theron and Scarlett Johansson in a number of comments. It was not only the colour that got people talking, as her new fringe seemed to inspire a change of hairstyle for a few of her fans. "OK, I'm about to cut my own fringe," one particularly devoted follower commented.
