Hugh Jackman has asked fans on social networking website Twitter.com to tell him about their favourite charities - so he can donate $100,000 (£67,000) to the most worthwhile organisation.
The X-Men star has invited fellow 'tweeters' to recommend causes they believe will most benefit from the windfall, and he has vowed to give the generous sum to the selected charity on behalf of the person who can deliver the most convincing and impassioned plea - within the short textual limit the website allows.
Jackman writes on his official Twitter page: "I will donate 100K to one individual's favourite non profit organisation. Of course, you must convince me why by using 140 characters or less.
"The more passion shown for your charity the better! Get the support of your friends and teach them the importance of giving."
The Australian actor's announcement comes less than a week after he was forced to admit he had recruited an assistant to update his Twitter.com page - following an embarrassing blunder in which his blog mistakenly referred to Sydney's famous Opera House as the 'Opera Centre.'
