Luke Bryan had a very embarrassing moment at a recent concert…

According to Taste of Country, the country star was gyrating his hips while performing when he had a sudden realization:

The fly on his pants was open!

Bryan explained the situation during a recent appearance on The Tonight Show Starring Jimmy Fallon:

“In all my years — never. I’ve fallen off stages, forgot words, said the wrong city — first time, fly down. I look down and my jacket or something that I had on was taking all of the paint off my guitar. I’m like, ‘Oh my God, my jacket’s destroying my guitar so I ran off, did a wardrobe change and through that, just forgot one small detail … not small detail, you know what I mean.”

Maybe this was all a ploy to steal the title of Sexiest Man Alive from Blake Shelton….
