Lady Gaga pulled out all the stops for her massive Super Bowl LI halftime show and boy did she deliver! The singer started out on the roof of Houston's NRG Stadium in front of hundreds of red, white, and blue color-changing drones before taking a cable-assisted leap down through the roof to the field below to kick off "Poker Face" with an explosion of pyrotechnics. All in all, it was an incredible show that both looked and sounded fantastic from start to finish. What was your favorite part?
