The 2015 Country Music Awards is always one of the biggest parties of the year. Last night, the best artists in country music gathered in Nashville to celebrate to 49th annual CMA's. It was a huge night for Chris Stapleton, who took home three awards and gave a special performance along with Justin Timberlake.

The pop star and Stapleton stunned the crowd as they sung a beautiful duet of "Drink You Away" and "Tennessee Whiskey." The mix of the different genres of music worked perfectly as the two traded verses and guitars.

One of the more interesting pairings of the night featured rock band Fall Out Boy performing with Thomas Rhett. The artists mashed up two if their songs "Crash & Burn" and "Uma Thurman" and the rock vibe fit Rhett's voice nicely. 

Other highlights from the night included Miranda Lambert, Blake Shelton, Carrie Underwood and John Mellencamp with Keith Urban.
