Actors contribute to the relief effort

George Clooney is donating $1million to help the victims of the Haiti earthquake.

The actor, 48, has also organised the Hope For Haiti telethon, which airs in the US tonight.

‘It’s a big world out there, and we all have a lot of responsibility to look out for people who can’t look out for themselves,’ he tells MTV.

‘So what we can do is first and foremost, raise money.’

George made a separate $1million donation last week through his Not On Our Watch charity.

Leonardo DiCaprio, 35, has also given $1million to the Clinton Bush Haiti Fund for Haiti.

Meanwhile, Madonna, 51, and Beyonce Knowles, 28, are the latest acts confirmed for tonight’s Hope For Haiti telethon.

Madge performs in New York while Beyonce appears in London alongside husband Jay-Z and Twilight star Robert Pattinson, 23.

The Hope For Haiti telethon will air in the UK on MTV on 23 January from 1am.
