The track - a co-write between Eilish, Khalid, and the former's brother Finneas (who also produced it) - follows the 16-year-old star's first EP Don't Smile At Me and is out now via Polydor. It arrives ahead of her pink Record Store Day 7", which features an acoustic version of her song "Party Favor" and a cover of Drake's "Hotline Bling".

Khalid had a busy 2017 rising through the ranks, and released one of our favourite singles of the year and one of our favourite albums of the year.
