NASHVILLE — Carrie Underwood dazzled with her performance at the 2009 CMA Awards Wednesday night.

The 26-year-old Underwood sang her hit song "Cowboy Casanova" in a sexy outfit that left her co-host, Brad Paisley, speechless.

Underwood took the stage wearing a long white peignoir with what appeared to be purple sequined hot-pants exposed underneath. She arose from a sofa amidst a bordello-red backdrop as her back-up dancers shadowed her dressed in black bustiers.

"How hot was that dress?" Paisley quipped after Underwood's performance. "You wouldn't believe the view that Little Jimmy Dickens got backstage. Paramedics say he's been stabilized!"
