Footage of the moment is currently circulating on social media (watch below). At around the same time, the star also changed their Instagram pronouns to he/they, according to reports this weekend. (At the time of writing, Jack's account does not appear to contain pronouns.)

"I'm bi..." the 17-year-old replies, before adding in a reference to Pixar's Luca: "Silencio Bruno!"
