A new preview has surfaced for MTV's forthcoming Britney Spears documentary, 'I Am The Femme Fatale'. 

The special programme will be shown on the music television channel on Sunday, April 3 and goes behind the scenes of the making of her seventh studio album, 'Femme Fatale', the recording of her Will.i.Am collaboration 'Big Fat Bass' and also of her day-to-day life during her new record's promotional period. 

An initial trailer was originally leaked at the beginning of the week, but this new one is extended and gives followers of the 'Till The World Ends' singer a real taste of what to expect.

Watch the trailer for the exclusive one-off show, which looks like a must for any Britney Spears fan, here:
