The Britain and Ireland's Next Top Model judge told her she looked like a chav two years ago - but it seems the insult has stuck with the singer.
At the time, her then-husband Ashley Cole was publicly dodging handfuls of cheating rumours and she's said she was 'really fragile'.
The Welsh fashion designer told her she looked terrible with her red hair while they were both at Sarah Harding's Halloween party.
The singer has now taken her time to voice an opinion against the man who told her to sack her stylist.
In an interview with The Sunday Times Style magazine, Cole said: "I will never have a working relationship with that man again.
"You have no idea how he ranted and raved. It was at a time when I was really fragile and vulnerable. I was, like, you have no idea what I'm going through."
Meanwhile, the 29-year-old also revealed how she keeps her tiny figure in shape - by having Japanese food delivered to her house daily by swanky restaurant Nobu.
But she admitted to being obsessed with anything sweet when it comes to food.
She said: "The sicklier the better. When I'm good, I'm very, very good, but when I'm naughty, I'm naughty in the extreme."
