Dr Who finds himself on the end of a tender kiss from Kylie Minogue, according to a leaked storyline from the upcoming Christmas Special of the hit show.

The one-off episode will be set aboard the Titanic, which has become a spaceship run by villain Max Capricorn.

Dr Who, played by David Tennant, must team up with Kylie’s character – waitress Astrid Peth – to save the earth from Max’s evil plans for domination.

Along the way, the diminutive pop princess hops on a box to plant a smacker on the lucky Time Lord.

But there will be no long term romance – at the end of the seasonal show Kylie disappears into space.
