The 45-year-old fashion designer - who launched his eponymous clothing label 20 years ago - has admitted his life changed for the better when his close friend Jade Jagger, 45, recruited the help of the 43-year-old fashion icon to grace the runway with her in his catwalk show in 1997.

Speaking in a new episode of 'Fearne on Fashion', which is one of The Huffington Post UK's 10-part video series, the creative mastermind said: "I'd made a few pieces that found their way into the hands of Jade Jagger. She and I became really good friends.

"Months later I'd made this collection. She said we need to talk models, 'Who do you want?' She said; 'Shall I ask Kate?' I said: 'Kate who?'

"A couple of hours later she came up the stairs.

"It snowballed and with that first show it became this big overnight thing."

And the mogul has admitted his first encounter with the blonde beauty was not as glamorous as one would assume, as the pair sat on the floor of a bedsit eating a takeaway.

He explained: "We sat on the floor in this bedsit eating a McDonalds and looking at this rail of seven dresses - I'd only made seven dresses - and she said: 'I'll do it, but as long as I can wear that dress'.

"I was like; 'Darling you can wear whatever.'

"I love where my business is going 20 years on, it's taking another form."

Meanwhile, the entrepreneur has admitted he has kept hold of every garment from all the fashion shows he has ever put on, and has even ordered them in date order.

He said: "This is my archive, so it's basically every garment I have ever sent down the runway from the last 20 years, and it's kind of chronological. It goes from 1997, the dress that Kate moss wore back there, to modern day."
