Filming for the upcoming Christmas special of Doctor Who appears to be underway at the moment, with cast member Millie Gibson having been spotted on set this week.
The actor, 18 - who is best known for having played Kelly Neelan on Coronation Street - had been unveiled as the latest companion, Ruby Sunday, just a few months ago.
Millie - who left the ITV soap last year - will appear in the beloved BBC show with Sex Education star Ncuti Gatwa, 30, who becomes the latest actor to play the Doctor.
