Kidman's younger sister looks older than her

Melbourne (ANI): Nicole Kidman"s sister Antonia is three years younger to her, but at a recent event she looked quite older than her famous sis.

Although the Australia actress had earlier described her TV presenter sister as her ''other half'', people witnessed a big contrast when Antonia appeared for a television awards ceremony this week. Antonia, 38, a mother-of-four showed off her toned legs and slim physique in a short dress and towering heels.

But, her smiling face revealed a little too much maturity for her young age— the skin around her eyes and mouth bore the laughter lines typical of a woman nearing 40. And although Nicole has crossed the benchmark, she looks as if she might have been frozen in time, reports The Courier Mail.

The actress" unlined look has left many people speculating that she has had botox treatment to maintain her youthful glory, which Nicole denies vehemently. Instead, she has put her youthful looks down to ''drinking lots of water, eating fruit and doing yoga''.
