"You may all know me as Lady Gaga, but tonight I am Lady Haha. Who's ready for some topical monologue jokes, yeah?" Gaga said. "Donald Trump is launching a nightly news show on Facebook which will stream Trump's rallies. It'll be kind of like airing my concerts, except instead of Little Monsters, there's actual monsters. And according to the show's creators, the programming is expected to really grab viewer’s by the p***y."

Lady Gaga spent the rest of the night with the house band and performed her new single "A-YO." Watch below and be sure to purchase your copy of Gaga's brand new album Joanne via iTunes, Amazon, or at your local record shop!
