Britney Spears is set to release her "explosive" video diaries.
The 'Toxic' star - who lost custody of her two children before being admitted to a psychiatric ward earlier this year - has been filming herself for the past six months and plans to show the world what she has been through by making the tapes public.
A source said: "If she does decide to go public with the footage, it will be explosive. "Although some of the footage is really sad to watch, especially the parts where she is close to breakdown - others are dynamite."
Britney's former boyfriend Justin Timberlake and her ex-husband Kevin Federline - who co-starred in her MTV reality show 'Britney + Kevin: Chaotic' with - are said to be concerned the singer will reveal intimate details about their relationships.
The source added to Britain's Daily Mirror newspaper: "Justin Timberlake and her ex-husband Kevin Federline are terrified the material will end up on the internet. "Or, even worse, Britney will agree to another MTV documentary and release some of the footage through official channels."
In January, it was reported Britney's paparazzi boyfriend Adnan Ghalib was trying to sell six video diaries of the troubled pop princess for $2 million. The clips are believed to have shown the 'Gimme More' singer "ranting, raving and weeping" and talking about herself in the third person.
