Fans of cult sci-fi series Doctor Who could be in for a real treat this year, with the news that pop diva Kylie Minogue may star in an upcoming episode of the hit series. Based on the adventures of an English time traveller, Doctor Who originally ran from 1963 to 1989, before being re-invented in 2005. Now, Minogue is reportedly set to star in the 2007 Christmas special, alongside the latest Doctor, actor David Tennant. "The Doctor Who team are delighted they've got someone as sexy and high profile as Kylie," a BBC insider has allegedly revealed.
