Britney Spears is setting the record straight about her head-shaving episode, alleged sex romps and bitter divorce in a candid new documentary.

The programme – which has been bought by Sky 1 – is sure to be the most eagerly-anticipated of the year.

Cameras followed the pop princess for six months as she slowly but surely bounced back from her highly-public breakdown at the start of the year.
