Kate Moss doesn't say much for 26 years, then sit her down with photographer Nick Knight and she gabs away for 10 minutes straight.
In a cosy chat with the leading industry snapper, Moss opens up about life as a style icon - from shooting to fame at 14 and working with the late fashion documentary maker Corinne Day, to her much talked-about figure, being a "scapegoat" and how she thinks it's "weird" that her face can sell so many magazines.
With a reputation for avoiding public speaking and dressed in a black leather jacket and huge black out sunglasses that she keeps on throughout the chat, Moss looks like she may not be the easiest interviewee.
However, the Croydon-born supermodel comes across as warm, modest, family-focused and incredibly down-to-earth as she features in one of Knight's SHOWstudio films that tell the history of contemporary fashion photography through the eyes of models.
Sat in the photographer's studio in front of a laptop, she throws her head back in laughter as Knight acknowledges the relative formality of the set-up.
He then searches for famous pictures of Moss on the web and asks her to take him through the background of some iconic shoots, casually throwing in questions about her legendary reputation and enduring appeal along the way.
Knight also released this 1995 fashion film of a a 'day in the life' of 20-year-old Moss shot by Jason Evans as a commentary on society's "obsession with images of celebrities and our voyeuristic tendencies when it comes to icons".
Focusing on a topless black and white picture of the model as a teenager that was shot by Day for The Face, the 40-year-old admits that she was self-conscious about her figure at the time.
“I was really embarrassed about my body, very, very self-conscious,” she says. “They came out when I was still in school.”
Knight then touches on the subject of her much-scrutinized "waif" figure, confirming "I know from working with you, you do eat."
"Yes, I was just really young and thin, that's what happens," she says.
Moss becomes animated as she talks about her 11-year-old daughter Lila Grace. "My daughter is tiny. My mum said to me 'oh, I was as skinny as you' and I was like 'right mother!' and that's what my daughter says to me now. She's like, 'Yeah, okay, you were really thin!' It's just age I think, you know. When you're a teenager and of course I was working in fashion back in the day, they didn't really feed you. The jobs I was working didn't have catering .. it was chips or whatever."
"I'm a fabulous scapegoat," she jokes, telling Knight that media reports blaming her for "heroin chic" in the '90s has led to an in-joke among her friends, who blame her for everything, including their own hangovers.
'My friends are like, 'Ugh, it's Kate's fault I am hungover.' And I'm like, 'Yeah, right! I didn't even see you.'"
There's also a charming moment when Knight addresses the model's superstar power and how magazine sales "rocket" when she is on the cover.
"I know it's weird though innit, I don't understand it," she says, shrugging, before quickly adding "let's not question it!"
The model is interviewed about her experience of being painted by Lucian Freud in another video chat with Nick Knight:
