Catherine Tate has filmed a special flashback sketch for one of her most popular TV characters.

The comedienne was spotted shooting scenes while wearing 1950s clothes in Kent last week - for a forthcoming Catherine Tate Show Christmas special.

According to the Daily Mail, Tate wants to take viewers back in time to meet a younger version of foul-mouthed pensioner Mrs. Taylor, whose colourful past was hinted at in the final episode of series three last year.

Tate was recently confirmed as the new companion for the next series of Doctor Who.
