Justin Timberlake and Jessica Biel will fill in for Leonardo DiCaprio as hosts of a fundraiser for Hillary Clinton on Tuesday.

A source familiar with the plans said that Timberlake and Biel now will host the event at their home, after DiCaprio was unable to return to Los Angeles before Wednesday because he has to complete a project in time for it to premiere at the Toronto Film Festival on Sept. 9. DiCaprio asked Biel and Timberlake to host the event after he couldn't make it.

DiCaprio is producing a climate change documentary, “Before the Flood,” with Brett Ratner, Fisher Stevens and Rick Yorn. The documentary is an account of how society can prevent the demise of endangered species, ecosystems and native communities across the globe.

Those featured in the doc include President Obama, Former President Bill Clinton, Secretary of State John Kerry, United Nations Secretary-General Ban Ki-moon and Pope Francis, along with a host of scientists and conservationists.

The lunchtime fundraiser is one of a series of events Clinton is attending in a swing through Southern California.
