Did you know that the guys of Rascal Flatts are solely responsible for Blake Shelton's transformation from small town Oklahoma boy to one of country music's leading men? The Grammy Award-winning trio spilled all the juicy gossip about the current CMA Entertainer of the Year winner during a recent visit to the popular late-night talk show, 'Chelsea Lately.'

"Absolutely. Every ounce of it," Joe Don Rooney boldly confessed after show host Chelsea Handler alleged that the 'Come Wake Me Up' trio single-handedly helped Shelton catapult to superstar status.

"We got him to cut that nasty a-- hair. We got him to move around a little bit on stage..." quipped Jay DeMarcus.

"It was like Billy Ray Shelton for a long time," lead singer Gary LeVox chimed in, poking fun at Shelton's years as a card-carrying member of the country music mullet club.

Though Rascal Flatts acknowledged that Shelton did open for them during his early years as a country singer, the playful banter regarding their friend and fellow country superstar was all in good fun.

The real reason behind the trio's appearance on the late night talk show was the release of their 'All Access and Uncovered' DVD package, a behind-the-scenes look at the recording of their recent studio album, 'Changed.'

The package includes exclusive performances of their group's biggest hits, including their recent No. 1 smash, 'Banjo.' The intimate film also includes in-depth and personal interviews from the band members in the studio, as well as an intimate glimpse of their lives on the road as one of country music's hottest tour acts.

To date, Rascal Flatts have earned 12 No. 1 singles, including 'Banjo' and 'Why Wait,' which were scored after the band joined the Big Machine label roster in 2010. The trio's 2012 gold-selling studio album, 'Changed,' also features their current Top 10 chart-climber, 'Come Wake Me Up.'
