Winners revealed for the 52nd ACM Awards.

ACM Country

The biggest and best country stars packed Las Vegas for one night only to celebrate the previous year in country music. Heading into the 52nd annual ACM Awards, Keith Urban, Miranda Lambert and newcomer Maren Morris led the nominations--scoring such nods as Album of the Year and Song of the Year distinctions. Over the weekend, several early winners were announced, including Florida Georgia Line's double wins for Single Record of the Year (for their massive "H.O.L.Y." ballad) and Vocal Event of the Year (for the Tim McGraw-assisted "May We All"). Also, Lori McKenna, the solo writer behind McGraw's "Humble & Kind," was named Songwriter of the Year, the first female to win the award--which was first handed out in 1965 to Roger Miller before being shelved for decades and resurfacing in 2011.

Other major nominees included Dierks Bentley, Thomas Rhett and Chris Stapleton in various categories, such as Album of the Year, Song of the Year and Music Video of the Year, respectively.

The 52nd annual ACM Awards aired live from the T-Mobile Arena in Las Vegas April 2 on CBS at 8/7c. Luke Bryan and Bentley returned as cohosts for the second year running.
