Shania Twain announced her plans for a Las Vegas show during a press conference that was streamed on her website earlier today and she also spoke to ET's Nancy O'Dell about her  return to the stage with a two-year residency at The Colosseum at Caesars Palace in Las Vegas. The country music superstar will bring all of her biggest hits in her new show SHANIA: STILL THE ONE exclusively to The Colosseum beginning December 1, 2012.  This comes as no surprise to me.
