OCEAN'S ELEVEN star George Clooney has become the latest celebrity to open up his wallet to help victims of Hurricane Katrina and is urging others to do the same.

Clooney has announced plans to donate $1 million (GBP555,500) to the United Way for its relief efforts.

The Hollywood actor, who is a member of the United Way Board of Trustees, says, "There isn't much any of us can do right now but pour money into this tragedy.

"We're all in this one together."
