Maren Morris, Brett Young and more country stars headed to Las Vegas, Nev., on Sunday night (May 20) for the 2018 Billboard Music Awards. Even Mason Ramsey (aka, "Walmart Boy") strutted his stuff in his signature cowboy hat and red bowtie on the awards ceremony's red carpet.

Readers can flip through the photo gallery above to see Morris, Young, Ramsey and others walk the red carpet ahead of the 2018 Billboard Music Awards ceremony. The event will begin at 8PM ET and air live on NBC from the MGM Grand Garden Arena. Kelly Clarkson is hosting the ceremony and is scheduled to perform at the show; she looked stunning on the red carpet in a glamorous black dress with a high slit up one leg.

Before the 2018 Billboard Music Awards began, Chris 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. Morris, who will be performing during the ceremony, was named Top Country Female Artist, while Florida Georgia Line earned Top Country Duo / Group Artist.
