WATCH: What has Nicole Kidman done to her face?
Nicole Kidman appeared on The Project last night to promote the new season of her hit HBO series, Big Little Lies.
The 51-year-old actress chatted to entertainment reporter Angela Bishop about the show with co-stars Reese Witherspoon and Laura Dern, but it wasn't the hugely popular drama that had people talking.

Nicole's age-defying complexion set social media abuzz, with many wondering the secret behind her flawless skin.
Her face appeared "frozen in time", according to Daily Mail Australia, with no lines or wrinkles visible even when the star broke into laughter.
Nicole, who has been married to Australian country singer Keith Urban since 2006, looked fashion forward in a powder pink silk dress and belted check blazer.
The mother-of-four wore her strawberry blonde hair loose around her shoulders and kept makeup to a minimum, highlighting her striking features with a slick of magenta lipstick and delicate pink blush.
In 2007, Nicole shut down plastic surgery rumours, telling Marie Claire she her appearance was "completely natural".
The Oscar-winner attributed her youthful looks to following a healthy diet, holistic beauty routine and wearing sunscreen everyday.
In February, a US report sensationally claimed Nicole Kidman was "obsessed with surgery".
According to the National Enquirer, the Hollywood star has “mapped out a bonkers blueprint” and is trying “every wacky trick in the book” in a desperate bid to stay forever young.
The publication further suggested the Australian-born stunner has spent "over $1 million on years of Botox and filler injections".
Nicole has always denied going under the knife, but the ex-wife of Tom Cruise has admitted to using a small amount of 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 told 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 biological 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 their famous mum.
'I just wanted them to be at work with me...' Nicole told The Project.
