The 26-year-old beauty looked sensational as she shared her stunning new look with her 608,000 Instagram followers.
Her highlighted white hair was styled in an up do and teamed with a dazzling bejewelled green headband.
The actress wore spider lashes and sparkly mint-coloured shadow to accentuate her blue eyes.
She simply looked magical.
Of course, fans of the star couldn’t wait to take to their keyboards to offer adoring praise to the young beauty as they saw her new style.
One follower chirped: “Wow, you look incredible.”
Another agreed: “Stunning Katie, you make a very beautiful fairy.”
While others couldn’t quite believe the striking resemblance between Katie and Peter Pan’s trusted sidekick.
One fan added: “Absolutely beautiful you make a fabulous Tinker Bell.”
And a second chimed in: “You really do look like Tinker Bell, so sweet, love it!”
Katie, played Sinead Tinker on the infamous cobbles, will now play Tinker Bell as she joins the cast of Peter Pan at Northwich Memorial Court this Christmas.
The starlet looked worlds away from her former character Sinead, who passed away tragically from cervical cancer last month on the ITV soap.
Prior to her heartbreaking death, fans were gripped as the tear-jerking twist of the full story unfolded.
Sinead had discovered that her husband Daniel had been unfaithful with Bethany Platt (Lucy Fallon) but decided to forgive him prior to passing away in her sleep.
Corrie continues tomorrow at 7.30pm on ITV.
