The 49-year-old actress has revealed she hasn't been told whether her alter-ego Missy, also known as The Doctor's nemesis The Master, will make an appearance in the next series of the popular BBC sci-fi show early next year.

She said: "I just don't know. I mean, I don't even know if she's coming back this season to be honest.

"As a freelancer which is what I am, I try to bag the next job, do it as well as I can and then move on to the next one."

However, although her fate is not yet known, the brunette beauty would love to bag a role in the spin-off 'Class'.

Speaking to the RadioTimes.com, she said: "I am an actor for hire, so if I'm free and it seems like the right thing to do at the time I'd grab it with both hands."

'Class' already stars former 'Coronation Street' actress Katherine Kelly and rising actor Greg Austin, as well as Fady Elsayed, Sophie Hopkins and Vivian Oparah.

The new BBC Three drama is set in Coal Hill school, which has a long history with the sci-fi series and was most recently featured in several episodes as the school at which the Doctor's former companion Clara Oswald (Jenna Coleman) taught at in Shoreditch, east London.

The programme - which is aimed at young adults - has been penned by 'A Monster Calls' author Patrick Ness and will consist of eight episodes, each lasting 45 minutes.

It is also believed that Twelfth Doctor Peter Capaldi will making an appearance in the series.

The plot of the drama focuses on the frequent visits by the Doctor to Coal Hill School which have made the walls of space and time become thin and now something from another world to bring war and fear to Earth.

The school was the setting of 'An Unearthly Child', the very first episode of 'Doctor Who' which was first broadcast in November 1963.

'Class' is expected to air on BBC Three later this year.
