Sian looked every inch the Geordie beauty in the snap as she pouted up a storm under a baseball cap.
She also wore heavy eyeliner à la Cheryl and lashings of bronzer on her high cheekbones.
Like Cheryl, she also had L’Oréal-worthy, luscious brunette locks, which she styled in voluminous curls.
Sian, who works as a Disney princess entertainer, saw her post liked over 800 times at the time of publication.
People were gobsmacked at the striking resemblance between her and the 36-year-old songstress.
One social networker commented: “I had to Facebook stalk as I thought this was a pic of Cheryl.”
While another added: “My God, you are so similar to Cheryl! Absolutely beautiful Sian.”
