In addition to winning Best of Las Vegas Awards honors like best resident performer/headliner, best production show, best bachelorette party and best bachelor party, Spears’ Las Vegas show helped usher in a new era for residency acts on the strip.

The city was once known as a place for older artists to live out their glory years. Thanks in part to Spears, Vegas reinvented itself as a place to see top younger artists, including Jennifer Lopez, Backstreet Boys, Bruno Mars, all of whom currently have residency shows. Lady Gaga announced that she, too, will begin a Vegas residency in late 2018.
