Rishi Kapoor plays the role of Veer Singh in Love Aaj Kal and he narrates his own love story with Harleen Kaur played by Giselle Monteiro to Saif Ali Khan's character.
But in the film, as he narrates to Saif his love story, he imagines his younger self as Saif, so that's how we see Saif playing the Sardar in the film. Though Kapoor gets married to Harleen Kaur's character the aged, Harleen shown with him in the climax is none other than his own off-screen wife, Neetu Singh.
Now one would assume when films are being made, main lead actors of the film do meet each other during the making. But surprisingly, this thing didn't happen in Love Aaj Kal.
Rishi Kapoor therefore ended up meeting his on-screen lover at the film's premiere in Delhi on July 30th night. On lookers say they both were extremely delighted on meeting each other and talked a while before going inside the cinema hall.
