The 52nd annual Academy of Country Music Awards took over Sin City on Sunday and it was all about the biggest country superstars on the planet, including Keith Urban, Miranda Lambert and Maren Morris.

Hosted by Luke Bryan and Dierks Bentley, it was a one-stop shop for all that is hot in the world of country music. Click here to see all the winners.

Florida Georgia Line Transformed Into Backstreet Boys… And Everyone Lost It

Viewers were treated to a pop and country crossover with Florida Georgia Line and the Backstreet Boys.

FGL and BSB combined forces for the country-folk single “God, Your Mama, and Me,” leading viewers to believe this was going to be one solemn and simple number. But the two acts didn't waste any time and transitioned into the former's hit, "Everybody (Backstreet's Back)." 

In what was probably the most energetic performance of the evening, FGL temporarily transformed into additional members of the group, chiming in for vocals, and yes, even performing the original choreography to the '90s pop gem alongside the five bandmates.

Everyone absolutely lost their sh*t. 

Country Music Pays Tribute To The Late Chuck Berry

Music stars Joe Walsh, Luke Bryan and Dierks Bentley paid their respects to the legend Chuck Berry with a tribute performance.

The three artists performed one of Berry's iconic hit "Johnny B Goode." Walsh played the heck out of his guitar while Bryan and Bentley belted out the song.

Carrie Underwood Joins Keith Urban For "Tricky" Medley

Keith Urban was the most-nominated act of the night, so it only made sense that the chart-topper took to the stage for a performance to celebrate his most recent album, Ripcord, alongside Carrie Underwood.

Urban kicked off his performance with the slow-grooving "Blue Ain't Your Color" with his four-piece backing band. Illuminated by a smoky blue setup, the superstar slowly transitioned into his most recent single, "The Fighter," alongside the former American Idol champ, where they jammed out as two background dancers offered the audience a choreographed routine similar to the alternate video to the track. 

Urban previously explained that merging the two cuts was "tricky" since he never performed a medley on an awards show stage. “Tempo wise and everything else was tricky, so we wanted to get that right," he explained. "Then for Carrie's and my performance, we wanted to incorporate the dancers from the video, but it was also tricky, so we just had to keep working on that.”

Miranda Lambert Wins Big

Miranda Lambert used the aftermath of her breakup with Blake Shelton and put it into her most recent album, The Weight of These Wings. It was a project that was honoured on Sunday with multiple accolades, including Album of the Year and Female Vocalist of the Year.

"Thank you for letting me use my heartbreak and sharing it with me," she said of the former award, referencing that split from Shelton. Stay classy, Miranda! 

Sam Hunt Serenades His Fiancée 

Sam Hunt appeared on stage to perform his new single "Body Like A Back Road.”

During his time on stage, he managed to do two things: once again show us all what a great performer he is, and also show us he is the greatest fiancé in the world — because he spent half of his performance sitting next to his fiancée Hannah to serenade her. 

With his arm around Hannah, Hunt basically serenaded her. And it was everything.

Tim McGraw & Faith Hill Perform "Speak To A Girl" For The First Time On TV

Tim McGraw and Faith Hill shared their new single "Speak To A Girl" a few weeks ago, but debuted their single live at this year's ACM Awards.

This was an extra special performance because 20 years ago, the couple shared the ACM Awards stage to debut their 1997 single "It's Your Love.”

Hill looked amazing in a midi sequin dress as she sang alongside her husband. There was also general #CouplesGoals happening. We all want to be Tim and Faith.

Thomas Rhett and Maren Morris Debut “Craving You

Thomas Rhett debuted his new collaboration with Maren Morris, "Craving You,” last week. On Sunday night, the duo performed their new song together for the first time.

Rhett kicked off the performance with his band, before Morris came out to join them.

Brett Eldredge's Cirque Du Soleil Inspired "Somethin' I'm Good At" Performance

Brett Eldredge performed his new single “Somethin’ I’m Good At” and he really took the Vegas theme to heart.

Performing mostly backstage and in the audience, his performance was full of Cirque Du Soleil inspired moments. From contortionists to a girl inside a bubble, the audience got the best of both worlds.

Our Hearts Couldn’t Take Cole Swindell and Dierks Bentley Doing “Flatliner”

Cole Swindell and Dierks Bentley joined forces to perform their new single “Flatliner.”

The two were having way too much fun together. Swindell even closed their set by expressing how much performing with Bentley at the ACM Awards meant to him and how he'll never forget this moment.

Reba McEntire and Lauren Daigle Take Us To Church

Reba McEntire and Lauren Daigle made watching the 2017 ACM Awards a religious experience by performing their new single, "Back To God.”

Daigle added a new spin to the song featured on McEntire’s latest album, Sing It Now: Songs of Faith & Hope.

McEntire got visibly emotional. The spiritual song and its message meant a lot to her and she tried her best to hold back her tears. It was definitely a beautiful, unforgettable moment.
