By Sarah Bull
She might be 57 years old, but Christie Brinkley is undoubtedly in the best shape of her life.
The stunning American model was seen drawing attention to her tiny waist in a tight blue dress and black belt as she attended the Cartier International Polo Event at Guards Polo in Windsor, Berkshire, today.
Eternally-youthful Christie teamed the outfit with a pair of black peep-toe heels, black handbag and matching hat to keep herself safe in the strong sunshine.

And the ensemble was enough for Christie to upstage fellow celebrities at the event, including Petra Nemcova, who looked amazing in a pleated yellow dress, and Amber Le Bon, who went all out in a floral maxi dress.
Christie is currently on UK shores performing in West End musical Chicago.
Having made her Broadway debut as Roxie Hart earlier this year, she came straight from New York to play the role in London.

And to make her feel at home, she has been reunited with Amra-Faye Wright, who had been playing Velma Kelly opposite her in America - but the girls are only performing for a limited season until August 6.
Christie was forced to push back the start of her four-week run after her mother Majorie Hudson underwent emergency surgery.
She apologised at the time, releasing a statement that said: 'I am very sorry for the inconvenience and changes to the schedule in London.

The supermodel then thanked fans on Twitter for their support, writing: 'Thank you for your cards , telegrammes (sic) and words of encouragement that help see us thru this terrible ordeal!"...'
However, Christie admitted recently she has no idea why she was originally approached to star in Chicago.
She said: 'I was so surprised they were interested in me for the part. I've done a couple of music videos for Billy Joel and I did a little show in Washington with Brooke Shields and Cheryl Tiegs.

'None of these things would make a producer go, 'That's our girl'. So I was surprised but interested. They must have me confused with somebody. But maybe I could just do an audition. D'you think?'
However, today Christie looked delighted to be taking a day off from Chicago and enjoying the activites at the polo.
