Halsey wasn’t scheduled to perform at Lollapalooza this year, but joined Charli on stage during her set to bust out the 1996 hit. Watch footage from the performance, below.
The pair are preparing to tour the US together shortly, and Charli will return to Australia later this year to support Sia on her ‘Nostalgic For The Present’ tour.
Meanwhile, Halsey — who was in Australia recently — says she’ll return down under “in less than a year”.
