Britney Spears leaves little to the imagination

BRITNEY Spears - who celebrated her 27th birthday in eye-popping style, barely squeezing herself into this revealing dress - is extending her run of shows at the O2.

The star (pictured with model Heidi Klum) will now perform on 3, 4, 6, 7, 10 and 11 June at the London venue.

The singer has been at the centre of a miming controversy since her apparent lip-synching performance on Saturday's X Factor, and has obviously decided to get the press talking about something else.

And it seems to have worked - as she struggled to maintain her decency, photographers could hardly keep their lenses off her.

The birthday bash took place at New York's Tenjune nightclub on Tuesday night, and also celebrated the release of the singer's new album Circus.

After a troubled year, the star has begun a comeback, with the new album and a first UK TV performance in four years.

However, as well as the X Factor mime, she disappointed fans by mouthing her way through another track from the album on US TV show Good Morning America.
