She said: “My agent was obsessed with [the actress] Nastassja Kinski at the time, who was in the film Tess, and thought I looked like her.
“So Tess it was. I was gullible and impressionable. Mind you, two weeks later I was in Japan then travelled the world. Paris, Milan, New York.”
Tess revealed that her mum Sylvia is “really the only person” who calls her by her real name, and “that’s not often”.
She continued: “She tends to call me ‘love’, so when she does say ‘Helen’ it can take me a while to respond.”
