Country artist Luke Bryan had the internet abuzz May 1 when he looked less than impressive during Ariana Grande's performance at the first ever iHeart Radio Awards

Luke Bryan is not impressed. The country singer had the Internet buzzing on Thursday, May 1, when the camera caught him looking less than impressed during Ariana Grande's performance of her new single "Problem" at the iHeart Radio Music Awards.

Donning a black sequined dress and white go-go boots, Grande performed her new single, which features Iggy Azalea—and when she broke out into dance, Bryan's face said it all. Rihanna was also caught reacting; however, the "Diamonds" singer was laughing while holding a glass of wine.

Bryan took to Twitter after the event, tweeting: "Wow me concentrating doesn't look good."

The "Play It Again" singer then got in on the fun, and changed his Twitter background photo to a screenshot of his not-impressed face on full display while he sat next to Blake Shelton

Grande went on to take home the iHeartRadio Music Young Influencer Award.

Other notable moments at the award show: Selena Gomez donned a maroon crop top and skirt while Usher danced on top of a table during his performance of the new Michael Jackson single "Love Never Felt So Good."
