The singer has recorded a version of `God Bless The USA` which will be available to download from iTunes and her official website on 06.05.11 and all proceeds from the sales will go to New York Police and Fire Widows` and Children`s Benefit Fund.

The charity was set up in 1985 to help the relatives of cops and fire-fighters killed in the line of duty and it has played a key role in assisting the families who lost loved ones when terrorists hijacked planes and crashed them into the World Trade Center on September 11, 2001.

The 29-year-old pop star originally recorded the track - which was penned and performed by country artist Lee Greenwood in 1984 - in 2008 for the election campaign of current American President Barack Obama but it was never released.

Piers posted a series of comments from Beyonce about the song on his twitter account which read: "We were all affected by the tragedies of 9/11 and continue to keep the families who lost loved ones close to our hearts ? Lee Greenwood, the writer of the song, is also donating his proceeds to help the 9/11 families ? Thank you Piers Morgan and CNN for helping to get the message out to everyone about this."
