Here's another behind the scenes shot of David Tennant and Billie Piper and in this one they're posing outside the TARDIS (because where else would they be?) for their new promotional pictures which would be used to promote the launch of Series 2 - David Tennant's first - back in 2006. This particular TARDIS partnership - the Tenth Doctor and Rose Tyler - is now so iconic that it's hard to believe there was ever a time without them. As a duo they were pretty much indestructible, as long as they weren't falling into the Void or being ripped apart on parallel universes. It happens to the best of us.
