Entertainer of the Year -- the biggest trophy of the ACM Awards. Of the current nominees, Luke Bryan has won it twice, and Garth Brooks has earned it six times. Jason Aldean, Eric Church and Miranda Lambert are also in the running -- but only one of the talented five country stars can win. Who will it be?

Aldean has been a country mainstay since 2005. His first, second, third, fifth and sixth albums are all certified platinum by the RIAA -- and his fourth record, My Kinda Party, is certified triple-platinum.  He won Male Vocalist of the Year at last year's ACMs and kicked off his 2016 We Were Here Tour in January.

Brooks is a Country Music Hall of Famer, and he's sold over 160 million records. His World Tour is his first in 13 years, after coming out of retirement. It was the third-ranking North American tour of 2015, grossing $114.9 million. Plus, Brooks is no stranger to ACM Awards, with 22 wins and 47 nominations under his belt.

Bryan has sold over 7 million records and celebrated 15 cumulative No. 1 songs. With five full-length studio albums under his belt and one album boasting six No. 1 singles (Crash My Party), Bryan is a true entertainer -- and he's the current Entertainer of the Year both for the ACM Awards and CMA Awards.

Church has five studio albums and a whole lot of clout behind his name. He's the most unpredictable of the nominees, and he has a cult following -- for good reason, too. He had a headlining tour in 2014-2015 and is co-headlining the Country to Country festival with Lambert and Carrie Underwood this year. Plus, he garnered five nominations at this year's ACMs.

The only lady who received an Entertainer of the Year nod, Lambert, has had a hell of a year personally and professionally, and both in the worst and best sense. Her most recent album, Platinum, is certified platinum, she hit the road on her successful Certified Platinum Tour and Roadside Bars & Pink Guitars Tour, and Platinum won the Grammy for Best Country Album.
