She said some friends completely cut her off following the article.
"(They said) 'I don't want to have to defend you anymore, I don't want you in my life any more'," she recalled.
"And it was that brutal. I wasn't ghosted – I was just cut off."
A decade on, she has written another piece in which she says she feels more beautiful than ever.
Writing for the Daily Mail, Brick said she "may be 51" but still has "charisma".
"That's far more seductive than having a Love Island-style face full of filler, spending hours in a salon to walk out with bizarrely painted fingernails or drop a small fortune on those awful hair extensions," she wrote in her piece.
Willoughby asked why, if Sam is trying to promote self-acceptance and confidence, she's judging other women who choose have cosmetic enhancements.
"I think the only reason I flagged that is because a lot of women are spending money they don't have on those hair extensions, fillers and nail art and we only have to look on certain social media/Instagram type accounts to see that it's becoming normal now," she responded.
"And I don't want to spend a fortune on Botox. And I want women to know it's okay not to have to do that.
"At the end of the day, you do you, and we should all celebrate women for what they are.
"But it's so normal now – having to go down that route of the, for want of a better expression, 'Love Island look' – and I think it's really important for women to realise that there is another option and the world won't end and you'll still have friends and you'll still fall in love if you don't do that."
