Taylor Hill is known for her flowing, brunette locks - which is why her latest Instagram snap came as a big surprise.
The Victoria's Secret model took to the social media site to debut a dramatically shorter 'do in a series of snaps.
Hill shocked fans when she shared the above photos, alongside the captions "Experimenting" and "Short hair don't care".
But is the haircut for real, or is the supermodel simply hiding her long locks (pictured a few days ago, below) under a very realistic wig?
With the Victoria's Secret Fashion Show a mere six months away, we can't help but feel Hill's contract probably doesn't allow for drastic hair changes.
But only time, and a 'fooled ya all' Instagram post or paparazzi snaps, will tell.
