If you want proof of the difference a Hollywood lifestyle can make, take a look at Nicole Kidman and her sister.

As she posed at an Australian awards ceremony last night, Antonia Kidman looked older than her famous film star sibling.

But at 38, Antonia is actually three years younger than 41-year-old Nicole.

The Moulin Rouge! actress, whose ivory complexion always looks smooth and unlined, has denied persistent rumours that she has had surgery to stay looking so remarkably youthful.

Antonia, a journalist and TV presenter in Australia, showed off her slim figure in a short black dress and killer heels.

The mother-of-four didn't take home any gongs, despite winning favourite female at last year's ASTRA awards.

Nicole, who wasn't at the ceremony in Sydney, has spoken about how having fair skin shaped her personality, and stressed that she can't stand being in the sun.

She said: 'When you're in Australia, you spend a lot of time inside if you're fair-skinned because you burn.

'My mum would keep me indoors, and I would read books as I wasn't able to go to the beach very often. I always felt like I wasn't the cool girl at school.'

She has also declared that she would never resort to Botox or 'go down the plastic route', saying: 'For an actor, facial expressions and emotions are really important.

'That's why I'll never have Botox. I've always been against that and seeing Botox on TV with all the swelling and pain put me off it anyway.

'The directors always allow actors with Botox but I just say. "No way, not for me".

'Drinking lots of water, eating fruit and doing yoga is what keeps me looking young naturally. I swear by it.

'I also use creams with natural ingredients to make wrinkles less visible. Everybody should try these things rather than going the plastic route, which I just hate.'

Some cosmetic surgeons have expressed doubt over her denials, however, with Dr Martin Braun last year saying he believed she was an 'enthusiastic user' of Botox.

The sisters have no other siblings and are very close to each other.

Antonia was a bridesmaid at Nicole's wedding to country singer Keith Urban in 2006, and later that year flew from her home to Sydney to be by Nicole's side to help her cope with her husband's alcoholism.

She also comforted her through her split with Tom Cruise in 2001.

In turn, Nicole helped Antonia through her own break-up with husband Angus Hawley in 2007, and is godmother to all four of her children.

The painful split occurred shortly after the birth of Antonia's fourth child, Sybella.

Angus did a stint in rehab for drug addiction and depression that same year.

Nicole told USA Today: '[Antonia] has been through a tough time recently, so I've been really blessed to be able to be there and help raise her kids, help with her children.'

The sisters also spent Easter together, along with other family members, in Nicole's £3million retreat in New South Wales, Australia.

The movie star has said of Antonia in the past: 'She's my best friend.

'I always say to her that I'm always there for her. We've been through a lot together, she and I.

'For a long time, we were each other's sole source of comfort.'

Although a celebrity in her own right, Antonia is less famous than her older sibling, but has said she has made peace with critics who accuse her of using Nicole's name to further her career.

In 2002 she said: 'While there are some parts of having Nic as a sister that have a downside - like people criticising me - there's so much upside that you just have to accept it.'
