The stunning 53-year-old actress admits she would consider having a little nip-and-tuck if she felt she needed it but has blasted people who go too far claiming they make her "uncomfortable".
She told America`s Elle magazine: "I`m all for a little something here and there - fine. It doesn`t matter to me if people have plastic surgery or they don`t, or if they do Botox. But when people don`t look like themselves anymore, that`s when you kind of go, `Oooh,` and it`s kind of sad. It`s uncomfortable for us, but if they`re happy with what they see in the mirror, does it matter?"
However, Michelle`s opinion is in direct contrast to a number of Hollywood stars who have recently blasted the entertainment industry`s obsession with youth.
Emma Watson said: "I do worry about the expectation to look a certain way. I find LA quite scary because of that - all those young people having plastic surgery. But the thing is, I don`t want to look like everyone else.
"I don`t have perfect teeth, I`m not stick thin. I want to be the person who feels great in her body and can say that she loves it and doesn`t want to change anything."
While Dame Helen Mirren has said: "The only thing I don`t like on young people is plastic surgery.
"The purity of youthful beauty is so fantastic to me that it`s horrific when young girls get fake things."
