Chelsy Davy attended London's Notting Hill Carnival on Monday (25.08.08).
The girlfriend of Prince Harry joined thousands of revellers at the event, and got into the party spirit by dancing behind a calypso music float with her friends.
The annual carnival sees the streets of west London awash with colour and music as onlookers line the streets to watch those taking part in the parade dance in costume.
Themes for this year's floats included Back from Space, Tutti Frutti Sweeties, Creatures Of The Earth and Paradise.
Michael Williams from London Notting Hill Carnival Ltd said: "The carnival is the perfect London spectacle."
Chelsy is will known for her love of partying. In July she was photographed on the shoulders of a male friend with her skirt over her head while making her way home from a race meeting in South Africa.
She also reportedly cheered and giggled as 100 men stripped off and engaged in a naked dash on the last day of the races.
