Carrie Underwood made an apperance on Jimmy Fallon's show last night and if you missed it, you need to find a way to see it!

First of all, they talked about how they used to have a country group that would sing 90's rap songs! This has me laughing so loud I woke my wife up. Carrie said their group was called, "C'rap." Here they are singing some songs...

The other awesome part of last night was the outfit that Carrie was wearing. HOLY SMOKES! Carrie's song with Aerosmith came out recently and she must still have been embracing her "inner rock-chick." Take a look at these pictures....
