The singer and X Factor judge, 31, posted the picture on Saturday (18 April) blaming her dad for the snap.
In the photograph, Cheryl looks fresh from the shower with a white towel wrapped around her wet hair.
Wearing a white bathrobe, she hasn't got a scrap of make-up on her face and looks flawless.
Alongside the snap, Cheryl wrote: "My dad is making me post this picture bc he said I am the double of my nana (his mother) when she was my age, and has a photo just like this but with a scarf on her head.. So here you go."
While some fans asked to see the picture of Cheryl's nana for comparison, most seemed awestruck by Cheryl's natural beauty.
One fan simply commented: "Beautiful."
Another said: "No you don't need make up... We are living in a society that makes you believe you need make up . Natural all the way."
Just days before, Cheryl had shared a cute throwback photo of her younger self with her mum Joan.
In the adorable family photo, Cheryl is wearing her brunette locks in pigtails and has a cheeky smile on her face.
