As any Doctor Who fan knows, later this year, the Doctor gets a new look. The next special will air this November, Matt Smith will be retiring as the current Doctor, and Peter Capaldi will assume the Doctor title before the end of the year. As interesting as the Doctor is, it is his companions that add an element of depth to the show. Billie Piper was companion to the 9th & 10th Doctor. Jenna-Louise Coleman is the current Doctor's companion. Which companion do you think is hotter?
