The annual Radio Times cover party took place on Tuesday evening and two very famous people from the Who world attended, David Tennant & Karen Gillan. They did a photo shoot together which you can see below:

Karen was invited because of her cover back in June for the episode "The Pandorica Opens" and David was there because of his "Single Father" cover. You can see more photos on their website here, where you can also see one with David Tennant and Steven Moffat.
