Welsh soprano Katherine Jenkins is following in the footsteps of Kylie Minogue by appearing in the Christmas episode of Doctor Who.
It's the first acting role for the singing beauty. But she will be able to benefit from the vast experience of her co-star Michael Gambon - Harry Potter's Dumbledore – who will join her in the episode.
Producers have promised something special for the show, which will be like: "All your favourite Christmas movies at once, in an hour, with monsters. And the Doctor. And a honeymoon."
For her part, Katherine said: "I'm over the moon to be involved in the Doctor Who Christmas special.
"I can't quite believe it as it's a part of the family tradition at the Jenkins household.
"I heard the news that I got the role on my 30th birthday and it was the best birthday present ever."
