“Charli likes boys but she knows I’d hit it,” Billie declares on the flirty collab.

The two have actually been trying to collaborate for many years: “i was speaking with Billie eillish [sic] about doing something. But we just couldn’t find the right song. I absolutely love her. She’s sooooo f-cking intelligent and her voice makes me melt ????,” Charli tweeted way back in 2017. Guess they made it happen!

The music video features the two climbing a giant mountain of bras and panties, and at the end, there’s a note: “All unworn undergarments will be donated to survivors of domestic violence through I Support The Girls.”
