Simon Cowell said Carrie Underwood could sing anything when she was on American Idol and she's proving him right.  Sunday, Carrie covered Guns N Roses' 'Paradise City' at CMA fest and KILLED it!

Carrie had quite a week last week.  She celebrated five years as a Grand Ole Opry member, performed a special tribute of Oklahoma tornado victims on the CMT Music Awards and then finished the week by getting pulled over for speeding.  But she put he blame on her husband.

At least she didn't pull a Reese Witherspoon and ask the cops if they knew who she was, demanding special treatment.
