It was Lorde's idea to work it out with Charli xcx on the remix
The internet went crazy when Charli xcx released a new version of her brat track, "Girl, so confusing" with its subject

No matter what happens for the rest of the year, this writer can claim with absolute certainty that Charli xcx’s “The girl, so confusing remix with lorde” will be one of the best music moments of 2024. Lorde’s instantly iconic verse on the (already very good) brat track—the one that was originally written about her—completely changed the meaning of the song from a one-sided musing on a confusing connection to a breakthrough moment where two old friends were truly able to “work it out on the remix.”
As Charli predicted, the internet did, in fact, go crazy when she posted a screenshot of a text from Lorde containing the incredibly raw lyrics to her verse. The pair garnered praise from all corners of the internet for the song’s authenticity and especially for the blunt but cutting words Lorde apparently wrote the morning she woke up to a voice note about the original track from Charli. Thankfully, as seems to be the case with much of the album’s excellent rollout, the genesis of the track is as organic as it claims.
