What happens in Vegas, stays in Vegas -- even Shania Twain and her successful Las Vegas residency, which is in its inaugural year. The singer has added 15 more dates to her run in Sin City, sliding into 2014.

Twain's 'Shania: Still the One' residency is currently booked through October and November of this year. This marks her first year at Caesers Palace. Clearly, things are going well if she added another batch of dates to the itinerary -- demand for the signer is high! The new run will span from Jan. 22 through Feb. 15, 2014.

The how is said to be quite the entertaining spectacle, featuring horses, a live band and a motorcycle that flies -- all of which you'd expect to find in Vegas.

You know what this means? That the boys in One Direction have more chances to see Twain's show. She extended a personal invite to the boyband after member Harry Styles posted a tweet praising the Canadian country singer. Perhaps they can carve time out of the schedule next winter and head to Sin City and let Shania show 'em how it's done!
