Bonnaroo is getting a little country this year! The eclectic 2014 Bonnaroo lineup now includes Dierks Bentley as part of the music festival's Bluegrasss Situation SuperJam.

The multi-genre Manchester, Tenn. festival will see big names, including Sir Elton John, Kanye West and now country star Bentley. The 'SuperJam' is a melting pot of artists who join one stage to play together for one night only. The 'Drunk on a Plane' singer will take the stage along with a slew of other talented artists.

Actor Ed Helms, who you may know from 'The Hangover' and 'The Office,' is also a musician and self-proclaimed bluegrass lover. He's hosting one of the 'SuperJam' nights and asked the country singer to join him. Shovels and Rope, the Lone Bellow, Lonesome Trio and Robert Ellis are just a few names on Helms' lineup. This is the actor/musician's second time returning to the Farm for a 'SuperJam.'

This particular 'SuperJam' is the only one specializing in bluegrass. The other nights include acts like Skrillex, Big Gigantic, Ben Folds and more. Bonnaroo takes place June 12-15 on the Farm in Manchester, Tenn. and Bentley will hold it down for country music when he takes part in the Bluegrass SuperJam.
