WILL SMITH has joined a global campaign to fight homelessness and raise funds to support 1 million people who are displaced or sleeping rough.

The actor will support The World’s Big Sleep Out, a campaign run into partnership with the Institute for Global Homelessness, Unicef USA, Malala Fund and Social Bite.

Speaking in a video promoting the campaign, the actor said: “Think for a minute about what home means to you.

“To me, home means conversation. It’s the place where my family comes together, and that’s the most beautiful part of home. But there are over 100 million people in the world that don’t have a place to call home.”

Around 50,000 people are expected to take part in the event on December 7. Participants around the world will sleep outside for one night and fundraise to tackle homelessness.

Smith will be appearing in Times Square, New York, to read participants a bedtime story. Other locations include Los Angeles and London, where Helen Mirren will read to those sleeping out.

The international campaign aims to get world leaders to take action to address the issue of homelessness.

“As well as raising money and investing in charities that make a difference, we want to send a message to the world’s political leaders to enact compassionate policy and find solutions for homelessness locally and the global refugee crisis that affects us all. We are a small, interconnected world,” Josh Littlejohn founder of The World’s Big Sleep Out and co-founder of Social Bite said.
