The guest actresses they have been getting for the show have been gorgeous. Here's what some of them look like without their stage make-up.
Raquel Cassidy- Miranda Cleaves, The Rebel Flesh.
Sarah Smart, Jennifer Lucas, The Rebel Flesh
Lily Cole as the Seas Siren, Curse of the Black Spot
Suranne Jones - the human Tardis; The Doctor's Wife. Sorry these pics are very big but she's very good-looking.
Talulah Riley's star is rising in Hollywood. She played the not-too-smart girl from Silence in the Library, (as a brunette). See her in Pirate Radio. She's in the beginning of the dream/bar scene in Inception-but if you blink you'll miss her.
