Billie Eilish created a buzz anew after gracing the stage at the Governor's Ball Music Festival in New York City on Friday. Besides her rocking performance, the Grammy-winning singer also called out security in the middle of a song.

While performing "Everything I Wanted," the 19-year-old superstar pointed to a crowd and rebuked the security personnel, yelling, "Security, why aren't you paying attention? Like for Real?"

A netizen with the handle @buwygidan shared a short clip of the incident via Twitter.

"When she yelled at security during eiw," the user wrote in the caption.

What exactly Eilish saw in the crowd remains unclear. According to Insider, several fans had to be "escorted out of the crowd, presumably for medical issues." At least three attendees were reportedly seen throwing up, though there were several signs and screens at the venue telling fans not to "overdo it" and proceed to the medical tent in case they feel unwell.

However, a source reportedly told the outlet what Eilish saw was not a medical issue and did not pose any threat to the safety of the crowd.

"One job, please," Eilish went on as she continued singing the song.

After a few lines into the track "Happier Than Ever," the singer paused again to check on the crowd.

"Everybody good? Are you OK?" she asked as the crowd cheered loudly in unison.

Despite the brief interruption, the "Bad Guy" singer took to Instagram afterward to post about her performance at the event, calling it one of her "all-time favorites."

"Last night was one of my all-time favorites THANK YOU GOV BALL," Eilish wrote in her post, which was accompanied by a short clip showing her and the crowd jumping to a song.

Recently, Eilish revealed she lost 100,000 followers on Instagram after she started wearing sexier clothes. She said many people have called her out for her sexy outfits in her snaps, particularly the one in which she wore a corset and lace bra.

"I lost 100,000 followers, just because of the boobs," she said in her cover story for Elle's October 2021 issue as per Page Six. "People are scared of big boobs."
