The Doctor and River won't be alone, though. They will also be joined by Greg Davies (Man Down, Cockoo, and The Inbetweeners) and Matt Lucas (Shooting Stars, Shaun of the Dead, and Little Britain).
Here's the official synopsis for the special:
It's Christmas Day on a remote colony and the Doctor is hiding from carols and comedy antlers. But when the Time Lord's help is requested he finds himself recruited into River Song's squad and hurled into a fast and frantic chase across the galaxy! King Hydroflax (Greg Davies) is furious and his giant robot bodyguard is out-of-control and coming for them all! Will Nardole (Matt Lucas) survive? And when will River work out who the Doctor is?
All will be revealed on a starliner full of galactic super-villains and at a destination the Doctor has been avoiding for a very long time...
You can catch a few glimpses in the BBC's Christmas trailer below:
"The Husbands of River Song" airs on Christmas Day. Be sure to check your local listings for times.
