Billboard crowned its 2018 Billboard Music Awards winners on Sunday night (May 20). Sam Hunt and Chris Stapleton were among the most-nominated artists at this year's iteration of the annual awards show, so it should be no surprise that they both took home trophies.

Before the ceremony began, Stapleton had already cleaned up in a number of the country categories: The singer-songwriter was, earlier in the evening, announced as the winner of Top Country Artist, Top Country Male Artist and Top Country Album. Hunt, meanwhile, took home Top Country Song during the final hour of the awards ceremony broadcast.

"My wife: Thank you for being so selfless this past year, sacrificing so much for me and our future," Hunt said from stage. "To all of my fans, we love you and appreciate you."

A complete list of the country winners at the 2018 Billboard Music Awards is below. Nominees for the Billboard Music Awards are determined through, per Billboard, album and digital song sales, radio airplay and streaming, touring, social engagement and key interactions with music fans. Billboard and its data partners track all of the factors over the 12-month period prior to the nominations announcement.
