Australian pop star Kylie Minogue is hoping to land a permanent part in hit British TV show DR WHO. The 39-year-old singer will appear as waitress Astrid Perth in the show's Christmas (07) special - but Minogue would like to become a regular cast member. She says, "It's not up to me but I know there has been talk that my character could be reintroduced at a later date. We'll have to wait and see. "I've always been a fan of Doctor Who and when you think how long it's been running, it is a series that is a unique piece of television history."
