Shania Twain is making a comeback in a big way.  She's not only at CMA Fest in Nashville this week, she's also teaming up with Taylor Swift to open the CMT Music Awards tonight with a "Thelma & Louise" skit.  Kid Rock, Glee's Chord Overstreet  and Kenny Rogers are also said to be part of the re-creation.  You can watch on CMT starting at 8 tonight.

Shania is also expected to make a big announcement this afternoon in Nashville.   She'll hold a press conference at 2pm central time, which is 3 our time.  The rumor is, she'll announce her run at the Coliseum at Caesar's Palace in Las Vegas starting December 1st, 2012.  You don't have to be in Nashville to see the press conference.  Watch it live at ShaniaTwain.com
