Troubled pop star Britney Spears has announced that she is going to donate the funds from an auction of her autographed CD to the United Nations (UN).

The Gimme More star has teamed up with a photo agency to put up a signed copy of her latest album Blackout on online auction site eBay.

All funds from the sale are set to go to the international organisation's children's fund, Unicef.

A press release issued by the X17 agency quoted the 25-year-old as saying: "I think it's important to give back and with the release of Blackout, this seemed like the perfect opportunity to give the fans a chance to bid on something to help children everywhere."

The auction officially closes on November 19th and so far the highest bid for the CD is $7,200 (£3,490).

Over the past few months Spears has been involved in a bitter custody battle for her two sons, with former husband Kevin Federline.

Previously the judge ruling in the case described the singer as a "habitual, frequent and continuous" user of controlled substances and alcohol and ordered her to submit to drug tests every week.

Spears has lost custody of her children and faced court orders regarding drug tests and parenting classes. She was recently awarded visitation rights to meet her sons every week but the court has not yet restored Spears' joint custody arrangements.
