The 48-year-old, who was once nicknamed 'The Body', does not think being younger always means being more beautiful, reported Contactmusic.
"I do not believe that youth equals beauty or beauty equals youth. It does not bother me becoming 50 at all, the alternative is death, so that is not an option. I rather like the idea of flowing on with life. I have had amazing life experiences and hopefully another 50 years of experiences ahead of me," the Australian beauty said.
Macpherson, who is a mother of two children, recently renewed her contact with cosmetics brand Revlon and says it makes her feel the attitude of brands towards people is changing.
"That tells me this is not an ageist society, and Revlon is a modern company," she said.
