Stars light up Victoria Derby

International stars of the screen and music scene helped brighten up a cold and blustery Victoria Derby race day in Melbourne.

While the social set were wined and dined in the Birdcage those in general admission stepped out in some more practical styles.

In the Derby Day entertainment stakes celebrity spotting is a tight race, with paparazzi jostling for a shot of Aussie-born Hollywood star Chris Hemsworth.

Beyonce's sister Solange Knowles also caused a stir inside the Birdcage - where VIPs gather to pose and perform.

Despite the cool conditions, racegoers worked up a thirst, and even the stars were worried about over-indulging.

While attendees were told to expect security hold-ups, thousands came through the gates trouble-free.

For those preparing to punt on another party, the weather should warm up for Melbourne Cup Day.
