The 39-year-old The Voice judge will play the character Earl in the animated film, and explains he kept being told to be as 'country' as possible.

"They kept saying, 'More country!'" he says. "I felt like I was doing a voiceover for Dukes of Hazzard."

Blake will join Jason Sudeikis, Peter Dinklage, Maya Rudolph, Kate MCKinnon, Keegan-Michael Key, Tony Hale, Bill Hader, Josh Gad and Danny MCBride in the film, which will hit cinemas in May (16).
