AUCKLAND (AFP) - A 17-year-old New Zealander whose TikTok anthem, Savage Love, has been viewed more than a billion times said on Wednesday (Oct 14) "it blows his mind" to have now topped the United States Billboard singles chart.

Jawsh 685 - whose real name is Josh Nanai - saw his viral instrumental remixed by US RnB star Jason Derulo and South Korean supergroup BTS to become an international mega-hit.
