Perry isn't the first star to debut a bleached eyebrow look. Recently, Kim Kardashian and Maisie Williams have each tried the trend.
And in the past, we've seen bleach blonde brows on Bella Hadid, Kristin Stewart and Madonna.
Plus, this wasn't the first time Katy Perry opted for the look. She first bleached her eyebrows back in 2016 for her Met Gala appearance.
This time, the reason behind Perry's bleached brows was simply business: she did it to accompany a Tinker Bell costume as the American Idol episode was all about Disney.
She also wore prosthetic pointed ears to make herself more like a fiary!
Perry stepped out on the stage donning a strapless green mini dress and fairy wings, making the bleached brows just one of many jaw-dropping pieces to her stunning look.
Perry has already said that she is ready to dye her eyebrows back to their normal state.
"Going to dye my brows back now," she wrote on Instagram.
Even if her bleached brows were a temporary change, Perry proved just how game-chaing this beauty trend can be. If you're thinking of taking the plunge, first try testing lighter brows out with makeup, like an eyebrow pencil or eyebrow powder, to see if the look works foryou.
Katy Perry has been a judge on American Idol for four seasons, after having first appeared as a guest judge on the show during season nine.
She often shows off playful styles in her clothes and makeup during the show, though her recent Tinker Bell look with bleached eyebrows was once of our favorites as of late.
