Hint - it involved some partying!

After her amazing performance and welcoming of Andrews to the stage, Gaga posted a sweet photo.

"Me right now. What a night. Congratulations to all the nominees, performers, and winners! Let's party!" she wrote with an emoji of a martini. In the pic, Gaga is on the floor, smiling after earning a well-deserved standing ovation from the Oscars audience.
