It has been announced that Graham Norton will be a guest star in the new season of Doctor Who on BBC One.
Norton's episode, titled The Interstellar Song Contest, will air on BBC One on Saturday 17 May - the evening of the Eurovision Song Contest Final.
Teasing what's ahead, the BBC said: "Calling all Eurovision fans! This season of Doctor Who will follow the Doctor (Ncuti Gatwa) and Belinda Chandra (Varada Sethu) as they travel to the 803rd Interstellar Song Contest - where planets from across the universe compete for the top prize, and along for the ride is the King of Eurovision himself, Graham Norton.
"Graham Norton joins the ensemble cast for the episode, which includes guest appearances from stars of stage and screen Freddie Fox, Rylan, Kadiff Kirwan, Charlie Condou, and Miriam-Teak Lee."
Russell T Davies, Doctor Who showrunner, said: "There's no song contest without the great man himself, and it was an honour to welcome Graham Norton to our studios in Cardiff.
"And it's not just a cameo, he has a whole plot twist all to himself!
"This is the wildest episode of all, and we're lucky to have Graham adding to the mayhem."
The new season of Doctor Who begins this Saturday, 12 April, on BBC One at 6:50pm.
