Amy Winehouse has reportedly spent £9 million on partying.
The 'Rehab' singer - who hasn't released a record since 2006 – has blown her fortune on wild nights out and a seven-month stay on the Caribbean island of St Lucia earlier this year.
Documents filed at Britain's company house show the three companies Amy owns are now worth £1 million, a sharp contrast from her estimated fortune of £10 million in 2008.
A source told Britain's Daily Star newspaper: "Amy's voice has made her a fortune, but her lifestyle costs a lot to maintain.
"There is still cash coming in from royalties. But a new album or tour would really help top up her coffers."
The 26-year-old singer is, however, still making money in royalties from her two albums, 'Frank' and 'Back to Black' - the latter of which has sold over 11 million copies.
Another source added: "The firms are not the only place she keeps her money."
Amy's finances are presently controlled by her parents Mitch and Janis, who were tasked with handling them earlier this year.
