Varun Dhawan promises to set the mood high at IIFA 2017. The actor will launch a song from ‘Judwaa 2’, the sequel to Salman Khan’s 1997 hit ‘Judwaa’. “For the first time in my career, I am paying a tribute to my father. I will be performing on songs from his films, right from ‘Swarg’ to ‘Main Tera Hero’ and ‘Judwaa 2’,” says Varun, who is preparing for the event which will be held in July. To launch the song, he is planning to dance on the newer version of ‘Oonchi hai Building’ from ‘Judwaa 2’.
