Sharon Stone has taken a musical turn, co-writing a song to benefit victims of Hurricane Katrina.

Stone worked with songwriters Denise Rich, Mark Feist and Damon Sharpe on "Come Together Now," which will be released as a CD single on Nov. 29.

Proceeds will benefit Habitat for Humanity, which helps needy families build homes, and Angels' Place, a Louisiana charity destroyed in the hurricane that helps terminally ill children.

"Every time this song gets played and every time this song gets bought, we're building houses and we're saving these kids," Stone said.

Celine Dion, Wyclef Jean, Patti LaBelle, Chingy, Joss Stone, The Game and more than a dozen other artists lent their voices to the song, available on iTunes since Oct. 17.

The single will also be part of a compilation album by the four major record labels, "Hurricane Relief: Come Together Now," which includes contributions from Elton John, John Mayer, Barbra Streisand and James Brown.

Stone, who is currently filming "Bobby," about Robert Kennedy, has been writing songs with various collaborators for the past year, she said.
