Popstar Halsey has apologised after accidentally calling for another 9/11 in response to a bad review of her latest album.
The 'Without Me' singer made the blunder when she reacted to Pitchfork's review of Manic, which awarded the album 6.5 out of 10.
"Can the basement that they run Pitchfork out of just collapse already", Halsey tweeted, presumably not realising that the music website is based in the One World Trade Center.
Having been alerted to the problematic nature of the statement given the terrorist attacks on the World Trade Centre on September 11, 2001, Halsey deleted the tweet.
According to Vulture, the 25-year-old followed up with an apology, which has also since been removed.
"ABSOLUTELY deleted it upon realizing this. Was just trying to make a joke! Intended zero harm," she reportedly wrote.
"Just figured I could poke at them back with the same aloof passive aggression they poke at artists with! Clearly a misunderstanding."
Halsey is scheduled to perform on Saturday Night Live this week, where it remains to be seen whether or not she'll address the mistake.
