He's sold more than 25 million albums, won two Grammys and has toured the world. But there's one thing Darius Rucker hasn't done that's high on his list: sing at the Grand Ole Opry. That dream will come true this Tuesday night, as the pop-turned-country singer is set to make his first performance at the sacred country music institution.

"When I was asked if I wanted to perform on the Grand Ole Opry, I yelled, 'Are you kidding me?!' I've been waiting for that my whole life,' " said Rucker. "To be invited where so many of the greatest country artists have performed is an honor, and I still can't believe it has been bestowed on me."

Rucker's first-ever country hit, 'Don't Think I Don't Think About It,' has cracked the Top 20 on the country singles charts. His first country album, 'Learn to Live,' will be released this fall.
