A whos who in country music is gearing up for the CMA Awards in Nashville tonight.  Brad Paisley and Carrie Underwood will host the show for the 4th year in a row.  And it's shaping up to be more than just a show with awards. 

Faith Hill will take the stage for the first time in 5 years to sing her new song 'Coming Home.'  Blake Shelton and Kenny Loggins will kick off the show by cutting loose with 'Footloose.'  A Glen Campbell tribute is planned with Brad Paisley, Keith Urban and Vince Gill.  Lionel Ritchie is also making a special appearance with Rascal Flatts, Darius Rucker and Little Big Town.  And if that's not enough, there's performances from Scotty McCreery, The Band Perry, Jason Aldean, Taylor Swift and The Band Perry, just to name a few.  Oh and they'll have out the awards to all the big winners too. Check out who is nominated.

The CMA Awards will air on ABC tonight at 8.  Check out behind the scenes rehearsals of Brad  & Carrie, Martina McBride, Faith Hill and The Band Perry.

Brad & Carrie may be hosting the show again this year, but it wasn't a lock. They had to audition and they had some stiff competition this year, according the ads they've been running.

If this promo is any indication of the comic relief we can expect on the show, it should be a night full of laughs. Brad is just one funny guy!
