Her next appearance was in Sandeep Vanga's romantic drama Kabir Singh alongside Shahid Kapoor. An adaptation of Vanga's 2017 Telugu movie Arjun Reddy, it was about the titular medical student (played by Kapoor) who goes on a self-destructive path and becomes an alcoholic surgeon after his lover (played by Advani) marries someone else. Despite receiving mixed reviews for glamorizing misogyny and toxic masculinity, Kabir Singh emerged as the highest-grossing Bollywood film of the year and Advani's highest-grossing Bollywood release, earning over ₹3.55 billion (US$51 million) worldwide to become one of the highest-grossing Indian films of all time.
