Beyonce has said the making of her upcoming documentary Life Is But A Dream was a therapeutic process.
She told the March issue of US Vogue that the "movie healed me in so many ways" and thinking about it makes her "want to cry".
The film addresses topics that the notoriously private singer normally avoids in public.
It chronicles her 2011 decision to drop her father Matthew Knowles as her manager, her miscarriage and even the rumours that she was faking her pregnancy with daughter Blue Ivy by using a surrogate.
"That was very odd," says the singer.
The documentary airs in the US on February 16 on HBO.
