The 10 star sometimes considers anti-ageing procedures if she sees photographs of herself looking "scary".
But she simply reminds herself that Botox and plastic surgery can often change a person's facial expression for the worse.
She says, "When you look at women who have had plastic surgery, they have lost something - usually an expression, something unique to their faces. They start to look the same. I've always admired the women who didn't do it, so I have to keep reminding myself I'm one of them and not the other.
"When I look at some photographs of myself, I think, 'Oh, I look alright.' But, in others, I scare myself; I wish I had my old skin."
