Serena Williams on Instagram: "When @kendricklamar and team called and was like ‘we’ve been trying to do something forever, what about this? We loved your crip walk at the Olympics after you won the gold medal.’ I’m like Super Bowl? Are you serious? When in the world would I ever be able to dance at a superbowl? (Never) let’s do it! I knew my winning dance after the @olympics would pay off one day. End of story."
