Justin Timberlake stepped in last minute to do his pal Leonardo DiCaprio a solid -- hosting a fundraiser for Hillary Clinton!
ET can confirm that the 41-year-old Revenant actor was all set to host the upcoming event on Tuesday night for the Democrats' nominee to the White House, but due to a scheduling conflict that kept him in New York, had to bow out. And that's when Timberlake, 35, and his wife Jessica Biel, bowed in.

Timberlake and Biel agreed to fill in as hosts and moved the fundraiser to their home. Let's hope the affair doesn't keep their 1-year-old son Silas awake!
