Replying to fans on Twitter, Halsey said that Experiment On Me was "hands down craziest song I’ve ever recorded. By a landslide. And rightfully so for Harley!!!!!"
She added in another tweet that it was recorded specifically for the Birds Of Prey soundtrack, and not an offcut from her forthcoming album Manic.
Other artists to feature on the soundtrack album include Doja Cat, K.Flay and Megan Thee Stallion.
Birds Of Prey hits cinemas on February 7 and sees Margot Robbie reprise her role as Harley Quinn.
