Carrie Underwood seems to be living life in the fast lane judging by songs including Last Name, Before He Cheats, Jesus, Take The Wheel and All-American Girl.

Despite romances with Chace Crawford and others, guys needn’t worry about her poison pen.

“Oh, no, I don’t write songs about the guys I date,” she tells me backstage at the CMA Music Festival in Nashville. “Every song, though, has to have a character in it. You definitely relate certain characters to certain people. Even if I write a song, I pick a song and sing a song, I have to relate them to certain people that I know. So I may relate a little bit to friends or family or guys that I have been around.”

The 25-year-old beauty is no hell-raiser after her shows.

“I go to bed. That’s my spot. Club bed. It’s wonderful, I tell you. Yeah, there’s just so much that goes on. You get out there and boy, it’s so dang hot here! And it’s humid and everybody’s sweating. I go home and I feel like that just makes everything that much more tiring. I feel like I’ve been running a marathon in the sunshine all day.”
