1. Billie Piper AND Matt Smith In Secret Diary Of A Call Girl
It was bad enough when Billie screwed PC Andy from Torchwood (nooo, anyone but PC Andy!) but then she had to take it one step further by getting down and dirty with the Eleventh Doctor himself. Yes, sticking with Secret Diary of a Call Girl now and it's the episode where two Doctor Who actors collided in more ways than one. It's safe to say that Belle de Jour encountered a diverse array of clients throughout her time as one of London's most high class escorts and every now and then she even came across - cue our final *ahem* - a future Time Lord. Before Matt Smith became a household name as the Eleventh Doctor, he made a brief guest stint as Tim in the ITV2 drama and well... you can probably guess what happened next, can't you? Let's just say, they didn't just go for a coffee and make idle chit chat about the weather, although that would've saved our Whovian souls an awful lot of heartache. At the time it wouldn't have been as bad but revisiting it now (which, let's be honest, you'll probably be doing as soon as you've finished reading thi... wait, no, come back!) is guaranteed to be about as awkward as a dinner date with a Dalek. Rose Tyler is in love with the Tenth Doctor, no? So what on Earth was she playing at getting up, close and personal with his successor, then?! As usual, for Doctor Who fans around the world, the lines between what's real and what's not are becoming increasingly blurred. Speaking of which, for some fans it's probably the realisation of a Doctor Who fan fiction they once read/wrote and the clips of Billie and Matt's 'encounter' have inevitably been included in countless fan made videos as an intriguing insight into what 'could' be happening on Rose's parallel worl. So at least some good has come out of it, eh? Still, the mind boggles. What did you think of this list? Are there any other times a Doctor Who actor played a character that destroyed your soul?
