Along with the big premiere of 'Doctor Who's latest episode "The Bells of St. John" this past weekend, the BBC released the momentous news that former 'Doctor' David Tennant would indeed be present for the upcoming 50th anniversary special, along with former companion Rose Tyler (Billie Piper)! Now, as production begins for the grand spectacle of 'Doctor Who's 50th anniversary, see the Doctor(s) reunite in the first photo of David Tennant and current star Matt Smith inside!

While much of 'Doctor Who's upcoming 50th anniversary remains shrouded and mystery, fans were giddy with delight this past weekend as the BBC officially confirmed actor David Tennant would reprise the role of the "tenth" Doctor, along with former companion and beloved 'Doctor Who' star Billie Piper. To commemorate the momentous occasion, Tennant and current 'Doctor Who' Matt Smith posed for a photo together after the read-through, giving us our first looks at the Doctors side by side.

Said show-runner Steven Moffat of the new episodes, including the upcoming 50th anniversary special:

It’s the 50th year of Doctor Who and look what’s going on! We’re up in the sky and under the sea! We’re running round the rings of an alien world and then a haunted house. There’s new Cybermen, new Ice Warriors and a never before attempted journey to the centre of the TARDIS. And in the finale, the Doctor’s greatest secret will at last be revealed! If this wasn’t already our most exciting year it would be anyway!

Upcoming guests for the remainder of ‘Doctor Who’ series 7 include Celia Imrie, Richard E. Grant, Warwick Davis, Raine, Scott and Tamzin Outhwaite, as well as mother and daughter Dame Diana Rigg and Rachael Stirling. Along with the reveal of David Tennant and Billie Piper, the BBC also revealed that UK thespian John Hurt would have a role in the 50th anniversary special.
