The actor and stand-up comic shares with ET how he's bringing together Brad Pitt and Jennifer Aniston, along with an A-list lineup. Originally slated to kick off Aug. 20, the virtual event, sponsored by Snack Pop, will now take place Friday, Aug. 21 at 8 p.m. ET / 5 p.m. PT, so it doesn't conflict with the final night of the Democratic National Convention. The event is hosted in collaboration with and benefits CORE, Community Organized Relief Effort, a nonprofit group looking to set up free COVID-19 testing sites and help communities in need during the pandemic. Fans can watch via CORE's official Facebook and TikTok pages, as well as LiveXLive.
