Florida Georgia Line debuted their latest hit "Can't Hide Red" at the 2019 ACM Awards in Las Vegas on Sunday — and one half of the duo, Tyler Hubbard, had the Internet buzzing with his stars and stripes outfit.

After taking the stage alongside Jason Aldean and band member, Brian Kelley, to perform the single off of their newest album "Can't Say I Ain't Country," social media users immediately went on Twitter to share their thoughts on Hubbard's look, which featured a matching American flag jacket and pants.

"Why is Tyler Hubbard wearing an American flag as a suit? #ACMawards," tweeted one viewer.

"Why did the guy from Florida Georgia Line look like he was wearing the American Flag?" one Twitter user asked.

Another person questioned: "That opening was horrible— what was Tyler Hubbard wearing???"

Meanwhile, other viewers loved the country star's look. "Tyler Hubbard’s jacket is my fave thing about the ACM Awards," wrote one person.

Before his performance, Hubbard, 32, hit the red carpet with wife Hayley — the couple is expecting their second child together — in color coordinating navy blue outfits.

FLORIDA GEORGIA LINE'S TYLER HUBBARD AND WIFE HAYLEY EXPECTING BABY NO. 2

Hayley, who cradled her baby bump, looked gorgeous in a simple deep blue gown, while Hubbard rocked a multi-striped suit with a blue undershirt, and matching shoes.

Back in February, the "H.O.L.Y" singer revealed the pair was expecting again with an adorable Instagram post.

"The Hubbard family is growing. We are excited to share that little nugget #2 is on the way. We are so thankful and can’t wait to see Olivia be a big sister. What do y’all think.... boy or girl?" Hubbard wrote alongside a photo of him kissing Hayley's stomach.
