She may be coming back to the X Factor next year, but in 2013 she'd headed to the Rovers.
She was spotted filming for her one off episode yesterday, and even got behind the bar with the lovely Michelle Keegan.
The glossy haired star is joining the Manchester soap as part of the Text Santa Charity broadcast, which will take place on December 20th.
Fans are thrilled to see their favourite pint-sized pop star make an appearance in the Coronation Street.
One wrote on her Instagram, "Are you playing a character or yourself? I hope you're fiesty when on Corrie!"
While another said, "Roll on the 20th December :-) about time ur on tv again :-)".
Michelle Keegan herself was chuffed to work with her.
