Carrie Underwood is the latest piece of the Grand Ole Opry. The Carrie Underwood united with the cast of the long-running country music show Saturday. Garth Brooks handled her official introduction and Vince Gill sang a duet with her. "This really seems like a great family to be part of," Underwood said, as she fought back tears. "I promise I'll do everything I possibly can to not make you regret it."

Carrie Underwood sold 7 million copies of her debut album "Some Hearts" and shot to superstardom almost overnight with hits including "Before He Cheats" and "Jesus, Take the Wheel." Her follow-up album, "Carnival Ride," came out last fall and has produced two No. 1s: "So Small" and "All-American Girl." Garth Brooks told her, "Nothing will last as long or be as important as this award right here. Being around you five minutes, I can see you get it. In coming from Oklahoma, I know you're sharp as a wit." Carrie Underwood becomes the newest young addition to the Opry cast in recent years, joining Brad Paisley, Josh Turner and Dierks Bentley. Opry administration says artists are invited to join based on their pledge to the show, as calculated by the regularity of their guest appearances, and their largely involvement to country music.
