Carrie Underwood is the newest member of the Grand Ole Opry.

The singer joined the cast of the long-running country music show Saturday. Garth Brooks handled her formal induction and Vince Gill sang a duet with her.

The former "American Idol" winner 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."
