Billie Eilish, Justin Bieber, and Hailey Bieber were seen wearing "ice out" pins at the Grammys. There appears to be a connection between this and a performance at Coachella, where Justin Bieber and Billie Eilish shared the stage. The nature and significance of their collaboration and the meaning of the "ice out" pins are not entirely clear, but it seems to have been a notable moment for Billie Eilish, who has been described as a childhood fan of Justin Bieber.
