Has a daughter Erin Johanna, born in January 2003, with her partner Twig Clark. Catherine became pregnant before filming Wild West (2002) and in the first series is very clearly showing under the baggy cardigans and hippy clothes she wears to play Angela.
On accepting her new position as the Doctor Who companion: I am
delighted to be returning to Doctor Who. I had a blast last Christmas
and look forward to traveling again through time and space with that
nice man from Gallifrey.
