Winner of the Young Influencer Award, Ariana Grande inspired some interesting reactions during her performance at the first annual iHeartRadio Music Awards.

Upon seeing the “Problem” singer’s transition to a dance routine, Artist of the Year winner Rihanna burst into laughter. While the giggling might have been more out of surprise or playful enjoyment than condemnation, it made for a notable television moment nonetheless.

Not as jovial, the reaction from country singers Luke Bryan and Blake Shelton was arguably more memorable.

Seated together at the awards ceremony, the two contemporaries, friends and ACM Awards co-hosts offered facial expressions plucked from the area between boredom and bewilderment.

Bryan, owner of the more animated reaction, joked about the facial expression in a Tweet Thursday night.

“Wow me concentrating doesn’t look good,” Tweeted the “That’s My Kind of Night” singer.

Playing into the online buzz, both Bryan and Shelton changed their Twitter cover photos to a screenshot of their now-infamous reactions.

Courtesy Shelton’s Twitter, that buzzworthy screenshot follows:
