LAS VEGAS (AP) - Shania Twain has added another 15 dates to her Las Vegas performing calendar.
Tickets for shows scheduled from Jan. 22 to Feb. 15 go on sale Friday.
The country superstar already has performances of "Shania: Still the One" set through October and into November to round out her first full year at Caesars Palace.
The five-time Grammy winner known for hits such as "Any Man of Mine" and "That Don't Impress Me" made her debut last December shortly after parading down the Las Vegas Strip on horseback.
Her show features trained horses, a live band and a flying motorcycle.
It's set at the Colosseum, home to fellow Canadian songstress Celine Dion.
