Listen to Blake Shelton on iHeartRadio | Listen to Hunter Hayes on iHeartRadio

Hunter Hayes is adding to the star power on tonight's season finale of "The Voice."  E! Online says the country star will perform his latest hit, "I Want Crazy" with the finalists.  Coach Blake Shelton will be taking the stage as well.  He's reportedly been tapped to cover The Beatles "With A Little Help From My Friends" along with his fellow coaches. 

Florida Georgia Line is also on board for the event.  The duo is expected to sing their hit "Cruise" with Nelly.  The star-packed show will also include performances from Cher, Christina Aguilera with Pitbull, OneRepublic and Bruno Mars in addition to naming the winner. 

Shelton has once again coached two hopefuls into the finale.  Team Blake's Danielle Bradbery and the Swon Brothers are vying for the title along with Team Usher's Michelle Chamuel.  The show will air on NBC at 8:00 p.m. Eastern. 

Team Blake has a very good track record on the show.  Throughout his run on the show Shelton has never had his entire team eliminated prior to the finale, and this isn't the first time two Team Blake members have made it to the finale.  Season three winner Cassadee Pope as well as runner up Terry McDermott were both on Team Blake.  Shelton also coached season two winner Jermaine Paul to victory, while Team Blake's Dia Frampton took second place on the inaugural season of "The Voice."
