David Tennant and Billie Piper have been reunited on the set of the DR WHO Christmas special, according to the News of the World:

They laughed and joked as they filmed the Christmas Special - after a year enjoying their own space.

Billie, 26, took a break from playing side-kick Rose to become a mum to Winston, now seven months old. And she filmed the third series of Secret Diary Of A Call Girl.

An onlooker at the south London set said: "Billie and David were joking about and seemed delighted to be working with one another again.
