Shania Twain is taking up residency at the Colosseum at Caesars Palace in Las Vegas. The music icon announced today her 'Still the One' concert series in Sin City, which will begin on December 1, 2012. She'll perform 60 shows per year for two years.

"This is a dream for any recording artist," Shania said in a press conference in Nashville Wednesday. "This is more than an opportunity, it's an exceptional gift."

So why the 15 month wait for the superstar's return to the stage? Well, Shania has been battling a medical condition called dysphonia, which she explains causes the muscles in her throat to squeeze her voice box. She blames the condition on traumatic events in her life, including the death of her parents in a car accident when she was a teenager and witnessing domestic violence as a child. But this is a hurdle Shania fully plans to jump ... and certainly in time for Vegas.
