Take Las Vegas and the NFL, add the world's hottest pop star, a love story that has social media spinning like a slot machine, two superb teams and you get what might be a landmark Super Bowl cementing Sin City's status as a global sports hub.
Already the United States' biggest sporting party, Las Vegas is promising a Super Bowl supernova around the Kansas City Chiefs and San Francisco 49ers showdown on Sunday.
