Kylie is said to be "thrilled" at being asked to join the cast for a special appearance and Doctor Who executive producer and head writer Russell T Davies confirmed: "We are delighted that Kylie Minogue will be joining the Doctor. "Doctor Who Christmas specials are always a joy and we feel very confident that this will be the most ambitious and best Christmas episode yet."
