Pop star Kylie Minogue is to have "a major lead role" in this year's Christmas special of Doctor Who.
Russell T Davies is "delighted" to have Kylie in the show
The star will join David Tennant for Voyage of the Damned, an hour-long show following on from the current series, which ended in the UK on Saturday.
"This will be the most ambitious and best Christmas episode yet," promised executive producer Russell T Davies, who has also written the script.
Filming is scheduled to begin in Cardiff later this month.
'Delighted and excited'
There had been rumours for several weeks that Minogue, who halted her Showgirl world tour for 18 months when she was diagnosed with breast cancer, would appear in the show.
And Davies said he was "delighted and excited" to confirm the 39-year-old's participation.
Minogue, whose debut single I Should Be So Lucky topped the charts in 1988, is currently working on her 10th studio album.
Last year's Christmas special of Doctor Who - The Runaway Bride - starred comedian Catherine Tate alongside Tennant.
She played a woman who was upset at being transported into space as she walked down the aisle on her wedding day.
The episode, broadcast on BBC One on Christmas Day, attracted an audience of 9.4 million.
