Ariana Grande may have reached the top of the charts with "Problem," but she did not impress fellow artists at Thursday's iHeart Radio Music Awards. Blake Shelton, Luke Bryan, and Rihanna looked far from impressed with her performance.

The Nickelodeon star wore a black sequin dress with white go-go boots and an '80s style pony tail. Her makeup was done naturally with simple black eyeliner and nude lips.

Grande began her performance with single "The Way" followed by new track "Problem" featuring Iggy Azalea.

While many seemed pleased with Grande's performance, others were noticeably not. Rihanna first had a blank look on her face, but was quickly seen laughing with a glass of white wine.

It did not do much for country artists Luke Bryan and Blake Shelton either. The camera cut to the "Country Girl" singer and Miranda Lambert with disapproving looks on their face.

Bryan later tweeted about the incident, "Wow me concentrating doesn't look good."

He then changed his Twitter background to a screenshot of the unimpressed duo.

Both reactions took social media by storm, with viewers weighing in on the incident.

"I'm watching #iHeartRadioAwards and the way that Luke Bryan and Blake Shelton just looked at Ariana Grande I can't stop laughing lmao," twitter user @srsly_psycho wrote.

Another user called @brettalana tweeted, "I'm actually crying cause Luke Bryan and Blake Shelton totally were covering themselves up from Ariana Grande's performance right now."

Grande took home the iHeart Radio Music Young Influencer Award, so we are sure she didn't mind the haters!

Shelton took home the award for Country Song of the Year. Other winners include Austin Mahone, Pitbull ft. Ke$ha for "Timber," and Pharrell Williams.
