Sporty Katy!

Kate Middleton paid a surprise Thursday visit to the Olympic Park in Stratford, East London -- and she got her game on right away!

Touring the Olympic Park and meeting with staff and dignitaries, the beaming Duchess of Cambridge, 30, was eager to play field hockey with Great Britain's official team.


Clad in ultra-tight coral jeans, hoodie and sneakers, Kate (who was captain of her hockey team at the Marlborough school) grabbed a stick and scored a goal!

"She had a quick go and got really into it!" an onlooker tells Us Weekly.

After Prince William's wife (they celebrate their one-year wedding anniversary next month!) presumably showers and changes, she's set to join father-in-law Prince Charles and Duchess Camilla at an art gallery in south London.
