Ben Affleck is to live on $1.50 (around 98p) for a day as part of a campaign to highlight issues of poverty in America. (Try doing it for a whole year. That'll make more sense).
The Oscar and Golden Globe-winning actor and director will stick to the budget as part of the Live Below The Line challenge in the US next week.
The campaign is hoping to raise awareness of the Global Poverty Project, which aims to 'increase the number and effectiveness of people taking action to see an end to extreme poverty'.
'One Tree Hill' actress Sophia Bush and musician Josh Groban are among the other celebrities taking part in the challenge, while Affleck will be taking part to support the Eastern Congo Initiative.
The stars will tweet about their experiences and let followers know just what they're eating and drinking.
“Last year we had over 15,000 people participate, and raised over $3 million,” said Michael Trainer of the Global Poverty Project.
“We're excited to leverage the support The Global Poverty Project has received from the campaign last year, and the Global Citizen Festival in Central Park.”
Since 2009, the campaign has encouraged people to take the challenge to live on $1.50 a day for five days.
Last year Hugh Jackman was among the celebs lending their sway to the excellent cause.
