The pop star was quizzed alongside her bandmates on music show Friday Download on Britain's CBBC network but when Nelson was asked about her boyfriend, fellow singer Jake Roche, and their shared love of hats, she feigned annoyance and stormed out of the chat.

She said, "Do you have a problem with me wearing hats? I've got my own style. I don't just copy my boyfriend. Oh, I'm not doing this guys."

After she departed the interview, her bandmates Leigh-Anne Pinnock and Jade Thirlwall rushed to offer comfort while Perrie Edwards stayed on the set looking stunned.

Having successfully pulled off the prank, Nelson ran back on to the stage laughing and assured the interview she was not genuinely offended by the line of questioning.
