The Girls Aloud star plays herself in the special episode of the ITV1 soap, filmed for Text Santa, and she arrives in Weatherfield in a bright red convertible mini.
Rovers Return bar staff Michelle, played by Kym Lomas, and Steve McDonald, Simon Gregson, can't believe their eyes when Cheryl walks through the door, asking for her friend Tina McIntyre - played by Michelle Keegan.
As we previously revealed, Cheryl is playing the part of Tina's long-lost friend in Corrie and has come to collect her, before taking her up to Newcastle for a family party.
Cheryl tells Michelle and Steve: "Hi...erm, I'm looking for Tina? We're supposed to be going to a Christmas party and then to my house for Christmas..."
Since filming with Cheryl, Michelle Keegan has spoken out about the moment she met her "idol", while also describing her as a "natural" in front of the camera.
She said: "They say never meet your idols but she was amazing. She is such a huge Corrie fan and she was genuinely pleased to be filming with us.
"I sat and chatted with her for ages which was lovely. She didn't need any tips from us all though, she was really good, a natural."
Talking about her Corrie cameo, Cheryl has also said: "It has always been part of my life, we'd all watch it as kids every night. It's surreal to be part of something I've watched my whole life.
"It's great to be able to support six wonderful charities and I really hope that this year's appeal makes a difference to many lives."
The full episode will air on tonight's Text Santa, which starts on ITV1 at 8pm.
