Collectively, the two Grammy-winning acts have scored more than 50 No. 1 singles and sold almost 80 million albums, according to a press release.

Jackson, a three-time Country Music Association Entertainer of the Year winner, topped the album charts twice last year with the platinum-selling "Precious Memories," which is a collection of gospel classics, and "Like Red on a Rose," which spawned current single "A Woman's Love."

Brooks & Dunn is the most-awarded act in CMA and Academy of Country Music history, according to a statement. The duo's most recent album, 2005's platinum-certified "Hillbilly Deluxe," launched their 23rd No. 1 single, "Play Something Country," and their award-winning hit "Believe."

Brooks & Dunn currently have a handful of their own headlining dates on the books, and will play a six-show run of NFL stadiums during Kenny Chesney's Flip Flop Summer Tour.

Newcomers Jake Owen and Catherine Britt will open the Jackson/Brooks & Dunn trek. Owen, one of the top-selling new male artists of 2006, is riding high on his hit single "Yee Haw," from his debut album, "Startin' with Me," according to a press release. Australian beauty Britt is currently on the airwaves with "What I Did Last Night," the first single from her upcoming RCA Nashville debut.
