As a part of this year's Text Santa charity appeal, superstar Cheryl Cole will be guest-starring on an episode of the hit British soap Coronation Street.

Cole's role on the soap will see her character arriving in Weatherfield in search of childhood friend Tina McIntyre (Michelle Keegan), whom she finds at the Rovers Return Inn. The two will travel to Newcastle to attend a Christmas party held by Cheryl's mother, though not all events go according to plan.

The cast of the show is also expected to be featured in behind-the-scenes footage of the 'Fairytale in Weatherfield" sketch -- featuring a special song by The Pogues' Shane MacGowan -- as part of the Test Santa online Advent Calendar.

Cole shared on Instagram two behind-the-scenes photos of her appearance. One is a screenshot of her and Keegan together, and is captioned "BTS Me and Tina! <3 her. #corriecameo. #textsanta."

Another is a collage featuring Cole standing outside Audrey's Salon and an outside shot of the Red Rover. The photo's caption reads, "BTS on Corrie for a cameo I am doing with charity text Santa. I had such an amazing day!! #textsanta I'm so excited."

Keegan also shared how excited she was to work with Cole on her own social media accounts, sharing another photo of the two together on her own InstagramKeegan also tweeted about the guest star, saying, "What a great day. Love her too much."
