Although Gillian insisted that she is not following any festive customs, one tradition that she is dabbling in is the Victorian Christmas ritual involving ghost stories.
Gillian also has recorded a Victorian Ghost story Mrs Zant and the Ghost, written by Wilkie Collins, which is part of a series of Christmas tales on Audible, including A Christmas Carol, a short story by David Walliams and many more.
Gillian said: "I love Victorian stories; Victorian ghost stories are even better."
And the Fall star - who has daughter Piper, 21, and sons Oscar, nine, and Felix, seven, from past relationships - enjoys listening to audiobooks with her family.

"Listening to audiobooks with family members is a wonderful thing to do.
"We often listen to on journeys, but this is something I would definitely choose to do with my family, specific to Christmas, around Christmas."
