“To the best fans on Earth ... You make it fun! You’re the reason I’m here. You motivate me!" Bryan writes in the video. "Work hard. Play hard. And never give up! We’ve made this moment together.”

In addition to Entertainer of the Year, Bryan is up for Male Vocalist of the Year, Song of the Year (for "Drink a Beer") and Vocal Event of the Year (for “This Is How We Roll" with Florida Georgia Line) -- and he's already won the Gene Weed Special Achievement Award. Bryan will also be co-hosting the evening's events alongside Blake Shelton, and he'll perform during the ceremony as well.
