The night featured eight performances from Gaga, including "Aura" and the title track, which had her dressed up in an all-white Michelin Man get-up, which was covered in those blow-up swimmies that kids often wear when they're first learning to swim.

Before launching into "Venus," she told the crowd they were blasting off into another world, and then jumped on a spinning stage that looked like a three-tiered wedding cake.

To introduce her latest single, "Dope," Gaga talked to the crowd about giving up drugs and alcohol, saying it was one of the hardest things she's ever had to do. "I still have a real hard time with it, but I wanted to say something about it tonight because I've watched too many great artists, too many friends, go because of those two things," she said. "I want tonight to be a change. I do not have to be high to be creative. I do not have to be drunk to have a good idea. I can sit with my thoughts and not feel crazy. I can do it without the dope."
