The 34-year-old star sported the bleached blonde eyebrows at her younger sister Kendall Jenner's 19th birthday party, said The Hollywood Reporter.
Kardashian revealed her new look on Instagram by posting a photo with supermodel Cara Delevingne.
In the photo, Kardashian appears sans her famous arches in favor of bleached blonde brows. She mentioned in captions that the bare-brow look is only for a photoshoot.
She followed up with a second photo, flaunting her look with the caption "#EyebrowsOnFleek," in which she and Delevingne, known for her perfectly shaped eyebrows, flashed the famous Kardashian pout.
