Academy of Country Music Awards 2017 Red Carpet

Country stars swarmed Las Vegas Sunday night for the 52nd annual Academy of Country Music Awards, which can really be summed up in three moments people are buzzing about on Monday.

Between Miranda Lambert, a university marching band, and '90s staple The Backstreet Boys, the ceremony did not disappoint.

See the night's most-talked about moments below.

Lady Antebellum's Performance With the University of Las Vegas Marching Band

The band's performance of "You Look Good," featuring the UNLV marching band, was easily the second best performance of the night, only to be eclipsed by '90s nostalgia, courtesy of a certain boyband you used to love.

Miranda Lambert Wears Her Heart on Her Sleeve to Accept Album of the Year Award

Lambert's acceptance speech for Album of the Year for "The Weight of These Wings" was a loaded one, speaking volumes of her personal life with ex-husband Blake Shelton.

"Thank you for letting me use my heartbreak and sharing it with me," Lambert said during her acceptance speech. One of her producers added, "In a day and age of sound bites, I just want to thank Miranda for being willing to look deep in her soul and bringing her life into her art. And guys, any young songwriters out there, tell the truth -- it's more interesting."

The Backstreet Boys Bring Down the House

Easily the most talked-about moment of the night, all five Backstreet Boys -- Nick Carter, AJ McLean, Howie D, Kevin Richardson and Brian Littrell -- reunited for the evening's high point moment. Their moves were just as on point as they were 20 years ago when their hit "Everybody (Backstreet's Back)" was released.

After the group performed their song with Florida Georgia Line, "God, Your Mama, and Me," the '90s boy band took the stage and surprised everybody with a rousing encore of "Everybody," which also featured the guys of Florida Georgia Line.
