On March 20, during the “ Break My Heart ” singer’s latest Radical Optimism Tour stop in Melbourne, Australia, Dua Lipa surprised the crowd with a cameo from Troye Sivan. As the singers entertained the Rod Laver Arena audience, they performed their not yet release remix of Dua Lipa’s track “Physical.”

The final two Melbourne shows were taken up another notch, however, with Lipa welcoming the original artists for a special duet. On Saturday (March 22), Troye Sivan served as the guest of honor, joining Lipa to perform a version of his Grammy-nominated 2023 single “Rush.”
