But while the scalpel may not be part of Australian star Nicole’s regimen, the red carpet fixture and ex-wife of Tom Cruise has admitted to using Botox in the past.
'I've tried a lot of things, but aside from sports and good nutrition, most things don't make a difference,' she was quoted as saying by German magazine TV Movie.
'I even tried Botox but I didn't like how my face looked afterwards. Now I don't use it any more and I can move my forehead again.'
Nicole is known to be very careful in the sun, and that extends to protecting her two daughters, Sunday, 10, and Faith, eight.
The American-raised pair of them make a guest appearance in the new season of Big Little Lies, joining husband Keith Urban and Meryl Streep on the show. It remains to be seen if they end up scooping some Golden Globes like mum.
'I just wanted them to be at work with me...' Nicole told The Project.
