iHeartRadio Music Awards viewers are obsessed with this Mariah Carey moment.

The singer went viral at Monday night’s show for her seemingly savage reaction to Tori Kelly and Muni Long’s tribute performance.

The duo performed many of the 55-year-old’s hit songs before she was presented with this year’s Icon Award.

During Long’s rendition of “We Belong Together,” the camera focused on Carey, who was seen turning her head and giving a serious side-eye look while others danced around her.

“this gif of Mariah Carey will go down in history,” one X user wrote, with another labeling the six-time Grammy winner a “meme queen.”

A third joked, “She was wondering why they didn’t book Ariana [Grande].”

Carey, however, was shown elsewhere in the tribute performance smiling along to “Always Be My Baby” and more hits.

Carey’s rep has yet to respond to Page Six’s request for comment.

The songwriter also made headlines for her candid comments about lighting while accepting her award onstage.

“Is the lighting OK?” she asked. “Because I don’t like bad lighting.”

In her ensuing speech, Carey gushed, “I still get excited when I hear one of my songs playing on the radio. It never stops being magical.”

While the Queen of Christmas did not walk the event’s red carpet, she wowed in a glittering black gown and curled hairstyle.

“Thank you, @iheartradio!! ✨❤️” she gushed via Instagram after the awards show.

Long, excited about the opportunity, reposted fan reactions to the tribute performance on her social media account and expressed her enthusiasm about paying homage to Carey in an interview with Billboard.

She broke down her top songs from the artist, including “Mine,” “Heartbreaker” and “My All.”
