Coronation Street fans have spotted that Alison King has starred in the soap before playing iconic Carla Connor.
Eagle-eyed viewers of the ITV soap have worked out that they have seen the 49 year-old actress on the show way back in 2004.
19 years ago, Alison guest starred for one episode as Mrs Fanshaw, a cougar who made quite the impact by bedding young Jason Grimshaw (Ryan Thomas).
This was two years before Alison joined the show full time as Carla, and has been on the show on and off for 17 years.
Back in 2004, Alison caused waves as a housewife who called in builder Charlie Stubbs (Bill Ward) to help her bleed her radiators.
He brought strapping young Jason along on the job, and soon a red robe clad Mrs Fanshaw only had one thing on her mind.

After getting Charlie out of the way, she proceeded to have her wicked way with Jason and the pair hit the sack together.
Of course, these days, Alison is far more famous for the role that has made her a household name.
Carla has battled alcohol addiction, failed marriages and plenty of drama at Underworld.
She is currently being drugged by evil Stephen Reid, who is trying to kill her so he get his hands on her business.
