The action-packed music video was filmed by Swedish director Jonas Åkerlund, who also shot Gaga's "Telephone
" clip. There's a car chase, Gaga riding a horse, explosions and flying beer cans.
Gaga did many of the stunts herself. "I won't tell you which ones I didn't do, but I will tell you that that's me the whole time on the car, when I'm on top of the car going really fast," she told Zane Lowe on Beats 1. "I was in high heels going from the trunk to the top of the car and then flying into the front seat. My mother, she was literally screaming at me. She was like, 'You have to do the Super Bowl!'"
