Carrie Underwood @ Fashion Rocks 2007

Carrie Underwood flawlessly works both her black and white outfits on the red carpet and on stage at the Conde Nast Fashion Rocks Concert at NYC’s Radio City Music Hall on Thursday. The country star wore Mikimoto jewelry with her little white dress by Georges Chakra.

The Idol champ rocked out on an electric guitar with Fleetwood Mac’s Lindsey Buckingham.

It appears that her performance was of “Go Your Own Way” by Fleetwood Mac, not “So Small,” the first single off her upcoming album “Carnival Ride”.

Fashion Rocks airs on Friday @ 9PM ET/PT on CBS.
