Twiggy

Twiggy was a guest at a party that Iris Wildthyme attended. Iris had a feud with her. (AUDIO: Whatever Happened to Iris Wildthyme?)

A young Sylvia Noble looked similar in appearance to Twiggy. Meeting her out of order, the Eleventh Doctor referred to her as such, giving no impression that he knew her in future events. (GAME: The Silent Street of Barry Island)
