'So far I've danced only in front of the camera and my bathroom mirror. So, I'm petrified,' Harman, who is slogging day and night to get his steps right for the performance, told .
'I'm performing my love ballad 'Milo na milo' from 'Love Story 2050',' he added.
Shiamak Davar will choreograph the number for Harman at the IIFA, which Remo has originally done in the film.
'And look at Shiamak's graciousness. He has decided to retain almost 60 percent of Remo's steps so that he doesn't feel the least offended. Normally, at events when other choreographers redo a number they transform it completely into their own idiom,' said Harman.
Harman has teamed up with Priyanka Chopra in the film, which is directed and produced by his father Harry Baweja. The film's promos are on air and it is scheduled to hit the marque in July.
When asked if Priyanka would join him on stage, he said: 'Not really, but she has her own performance. Now, of course, people will say she got me the IIFA performance, just as they are saying she got me 'What's Your Raashee'?' Harman ends sarcastically.
