Britney Spears goes all posh at the polo for new video

Demurely dressed in a vintage Givenchy frock with a matching wide-brimmed hat, Britney Spears could have easily passed for one of the society girls who frequent polo matches.

But the popstar, who's normally seen in jogging bottoms and tight-fitting tops, hasn't suddenly ditched her trailer trash fashion inclinations for a new image.

The singer was just playing pretty for her latest video filmed in Santa Barbara for new single Radar.

In the video Britney, 27, enjoys a polo match with a group of friends.
