On Sunday, Kevin Hart was the subject of a comedy roast that brought together a ton of comedians to brutally mock him - and each other - live on Netflix.

Host Shane Gillis was joined on stage by celebs like Tom Brady, Serena Williams, Lizzo, Pete Davidson, Dwayne Johnson, Regina Hall, Draymond Green, Usher, and Chelsea Handler - and that's naming just a few.
