Florida Georgia Line were guests at the 2019 Billboard Awards in Las Vegas on Wednesday (May 1), and they walked the red carpet in style.

Brian Kelley and Tyler Hubbard will be presenting during the awards show, but first had to show off their best looks. Kelley donned his signature wide-brimmed hat along with a white shirt with a blue-and-white plaid vest, while Hubbard put on an off-white suit to walk alongside pregnant wife Hayley in a pastel green gown. She's expecting their second child, and it's a boy!

The couple found out the sex of the baby on the Ellen DeGeneres show last month when the duo were on the show. Their first child, Olivia, was originally supposed to be a boy (according to doctors) before a scan confirmed that she was actually a baby girl. She will turn two shortly after the new baby arrives this winter.

FGL are nominated for several awards, including Top Country Artist, up against Luke Combs, Jason Aldean, Kane Brown, and Dan + Shay. Florida Georgia Line are also nominated for Top Duo/Group alongside Dan + Shay and Old Dominion, as well as Top Radio Song and Top Country Song for "Meant to Be" with Bebe Rexha.

This summer and fall, the pair will be headlining their Can't Say I Ain't Country Tour with support from Dan + Shay, Canaan Smith, Hardy and their "Up Down" collaborator Morgan Wallen on select dates.

This winter in November, the duo will return to Las Vegas once again continue their Vegas residency.
