Michael Jackson has written a song for the victims of Hurricane Katrina, his spokeswoman said on Tuesday.
Jackson co-wrote charity song We are the World in 1985
She said he hoped to record the track - tentatively titled From the Bottom of My Heart - with other artists and release it as a charity single.
In a statement Jackson said he would be "reaching out to others in the music industry to bring relief and hope".
"It pains me to watch the human suffering taking place in the Gulf region of my country," he said.
Jackson has been in the Middle East since his acquittal on child molestation charges in June.
However, spokeswoman Raymone Bain said he would return to the US to work on the single.
Jackson wrote We are the World with Lionel Richie in 1985 to raise money for African famine relief.

The hour-long special will be carried on major US broadcast channels and more than two dozen cable outlets.
It will also be shown in more than 95 countries, including the UK.
Celebrities are stepping up their efforts to bring relief to those affected by Hurricane Katrina via a variety of channels.

Green Day, REM, John Cusack and Moby have pledged to help find housing for flood victims through the political organisation MoveOn.org.
"As a band we felt promoting the service was essential - literally a matter of life and death," said REM's Michael Stipe.
Singer Harry Connick Jr returned to New Orleans on Monday to survey the damage at his father's home.
"It looks like pop's house made it through," he said. "Everything looks like it's pretty dry."
The jazz star has agreed to be honorary chairman of Habitat for Humanity's Operation Home Delivery, a long-term rebuilding plan for the hurricane-affected areas.

Connick Jr performed in A Concert for Hurricane Relief on Friday, which made headlines after Kanye West's outspoken comments against President Bush.
"George Bush doesn't care about black people," West said at the televised benefit in New York.
Actor Matt Damon has come out in support of the rap star. "I'm not a big fan (of Bush) so I let out a big cheer," he said on the TV show Access Hollywood.
"Hopefully Bush will come out now and address the issue."
Legendary New Orleans bluesman Dr John has also been critical of the authorities as he urged people to donate to relief efforts.
"If anybody in the government would've done something about the disappearing wetlands for the past 50 years, then this probably wouldn't have been as bad," he said.
And musician Prince has written two songs called SST and Brand New Orleans for download on his website. He will donate all proceeds to hurrican relief efforts.
