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.
