Penn, 51, made a rambling delivery, jokingly questioning why some of the A-list guests were at the charity gala'when you have people to f***' at other parties.

He then praised fellow Haiti fund raiser Paul Haggis, 'even though he was a Canadian whose parents included a man, a woman and a tree.'

He added: 'F*** 'em if people say you're just writing a cheque, but you're making a change'.

Passionate: The actor, pictured with Roberta Armani, Giorgio Armani and Petra Nemcova, made a speech urging guests to pay the f*** up' at the Haiti: Carnival in Cannes.

He continued that Haiti should be helped because it was just an hour away from 'the richest f***ing country in the world'.

Penn may have had a tipple or two, or three, but he was impassioned about supporting the people of Haiti although he said people had to 'fight the f*** out of politics' to get things done.

The rant continued when he demanded that guests bid for auction items.

'I want you to stay here and listen to the auction and beat the s*** out of each other to purchase them.'

The actor , who wore glasses as he made his speech, continued his blue streak.

He instructed women: 'Tell the man next to you, "I'm not going to f*** you tonight unless you pay the f*** up.'

None of the guests appeared offended by the tirade, which had many an A-lister in fits of laughter.

Some felt his spicey language gave the evening some electricity.
