Halsey is apologizing for an insensitive tweet about the One World Trade Center building.

It started when the singer, 25, hit back at the outlet Pitchfork, who shared a less-than-positive review of her new album, Manic, on Twitter. The review, in part, read, “Too much of this album sounds like the amorphous pop that you might associate with a miserable Lyft ride.”

In response, Halsey slammed the outlet. In a now-deleted tweet, she wrote, “Can the basement that they run p*tchfork out of just collapse already.”

The Pitchfork offices are in One World Trade Center, the main building in the rebuilt Twin Towers, which collapsed on 9/11.

According to Halsey, she had no idea where Pitchfork’s offices are located.

NBC reporter Ben Kesslen alerted the “Without Me” singer about the insensitive tweet: “Losing my mind thinking about the person on Halsey’s team who had to tell her she just called for the collapse of One World Trade.”
