From the SUN today:- KYLIE Minogue is set to solve a years-old Doctor Who mystery she IS the Tardis! Who buffs reckon the pop princesss appearance as waitress Astrid Perth in a Christmas special cracks an ancient code. Astrid is an anagram of Tardis, while Perth means part in Welsh, where the show is filmed so her name translates as part Tardis. And Kylie, 39, exits the BBC sci-fi hit by spinning into space as the Tardis is frequently seen doing. A BBC source said: Viewers have often been told the Tardis is a living organism. But mystery has always surrounded what it is and what gives it its powers. The elements we know about Kylies appearance all point towards her being the Tardis. The fact Kylie had a hit called Spinning Around is an added irony. But as usual with the show, fans will be left guessing the whole story. Meanwhile, a scene at the end of the last series in which a female hand picked a ring out of the Masters ashes has sparked rumours the character returns next series as a WOMAN. But to add to the mystery, there are suggestions that John Simm who played the Master returns in the New Year. EARLIER REPORT KYLIE Minogue will plant a tender kiss on Dr Who in the Time Lords Christmas special, The Sun can reveal. The tiny pop poppet has to climb on a box to snog the lofty Doctor, played by David Tennant. But romantics will be disappointed to learn there will be no lasting love between the pair. The seasonal spectacular ends on a sad note when Kylie, playing Dr Whos temporary sidekick, spins off into space in a strange half-form of herself. Kylies Christmas smacker is revealed in a plot outline for the show. BBC bosses have been desperate to keep it secret but The Sun has seen a copy. We can reveal the special is set on board the Titanic, which has become a spaceship run by arch-baddie Max Capricorn. The Doctor stows away on board and teams up with feisty waitress Astrid Peth, played by Aussie Kylie. Together, the pair must save the Earth from mad Maxs evil intentions. But they snatch a brief opportunity to get smoochy. Astrid tells the Doctor: You need someone to look after you can I come with you? He agrees. And according to the script, they share a good kiss. Last night a show insider said: Dr Who is one lucky, lucky, lucky time traveller. Who wouldnt want to be snogged by Kylie? The special ends with a stunning scene in which the Titanic falls from the sky and looks like crashing on Buckingham Palace. Kylie, 39, looked highly kissable last night at a preview of the musical Rent in London. CHILDREN IN NEED Who Needs Another Doctor? The Tenth Doctor meets the Fifth Doctor.
