Leonardo DiCaprio and Robert De Niro are offering a walk-on role in their new movie to a fan who donates to a new celebrity-driven Covid-19 fund.

Axar.az reports citing foreign media.

People who give to the All In Challenge will be entered into a prize draw.

The campaign was launched on Tuesday to help feed vulnerable people in the US and has already raised $5.6m (£4.4m).

Ellen DeGeneres, Kevin Hart, Justin Timberlake, Justin Bieber and many US sport stars have also offered donors a chance to get up close and personal.

Bieber has promised to fly to one lucky fan's house - once the lockdown is over - for a private performance of his 2009 hit One Less Lonely Girl.

Hart has offered a speaking role in his next movie, while Timberlake and Bill Murray will give a winner a round of golf.
