Comedienne Catherine Tate will make an appearance in the Doctor Who Christmas special, it has been revealed.
Tate recently won a Royal Television Society award for her show
The actress, famous for her catchphrase "Am I bothered?", will play Donna, a runaway bride, alongside lead actor David Tennant.
Writer Russell T Davies said the Tardis would be in for a "bumpy ride" with Tate on board.
Ms Tate said:"I was holding out for summer season at Wigan rep but as a summer job this'll do."
She made a preview debut in the last episode of the current series, broadcast on Saturday evening, appearing in the Tardis in full bridal wear.
The same episode was also the final show for Billie Piper, who has played the doctor's assistant Rose.
Mr Davies said: "Doctor Who and Catherine Tate is just the most irresistible combination, a genuine treat for Christmas viewing.
"After two years of travelling with Rose, the Tardis is in for a bumpy ride with Donna on board."
Last week it was revealed that Freema Agyeman would take over from Billie Piper as Doctor Who's new sidekick.
The 27-year-old former Crossroads actress will play Martha Jones in the next series, which begins filming in Cardiff later this month.
