So I was interested to read reports that Nicole Kidman has given up Botox and fillers.
If you look at her in earlier films like Dead Calm, she clearly had a natural frown line between her eyebrows – which were much lower then – and a very thin top lip.
Yet there she is 20 years on, with a shiny smooth forehead and well defined lips. Whatever she's having done now, it's a bit more subtle.
Maybe she has the same beauty therapist as Jennifer Aniston, who manages to stay so fresh without looking artificial.
Meanwhile I don't know what to make of 79-year-old Joan Collins's claim that she has never had a facelift.
She claims her good skin is down to staying out of the sun and piling on her make-up with a trowel.
Still, you can't help but like a woman who – when asked about the 30-year age-gap between herself and her husband – simply shrugs: "If he dies, he dies."
