Australian pop diva Kylie Minogue will join the cast of British science-fiction TV drama Doctor Who for a special Christmas episode, the BBC said on Tuesday. The hour-long episode, Voyage of the Damned, will start filming in Cardiff, Wales, in July. “It is an incredible thrill to be joining David and the entire Dr Who production for this year’s Christmas special,” said Minogue. “Dr Who enjoys a unique history and it is going to be very exciting to be a part of that.” Former television soap opera star Minogue returned to the stage last November with a sell out concert in Sydney after recovering from breast cancer. She is a really brave woman to have fought breast cancer successfully and then resume her singing career which is one of the most successful singing careers ever by a female artist. Her songs and the music in it has for long mesmerised her fans.
