Spears' 'Circus' wows London

Britney Spears thrilled a star-studded audience at the first show on the European leg of her 'Circus' tour - Lindsay Lohan and Jennifer Love Hewitt were among the fans in the audience in London on Wednesday night.

The pop superstar kicked off her run of concerts at the British capital's O2 Arena by descending from the ceiling on a circular trapeze, wearing a revealing corset and fishnet tights to sing her recent track 'Circus'.
