Jai (Fardeen Khan) is a fashion designer happily married to Geeta (Sonali Kulkarni). Riya (Urmila) is a budding model whom Jai gets to shoot. The twosome gets close during the photo sessions and the increasing proximity between them turns into love. Geeta comes to know of Jai's clandestine relationship with Riya and his libertine ways. Jai asks for forgiveness when Geeta confronts him. But Riya is madly obsessed with Jai and is prepared to go to any length to get him in her life, even if that means committing suicide or getting rid of Geeta forever. Pyaar Tune Kya Kiya showcases Urmila in a new sassy avatar with her hair finely cropped to shoulders. Grapevine has it that Urmila herself created the look of her character in the film—from selecting her clothes to losing weight to match the appearance of her character in the film. She looks stunning in the film. It is for a second time Urmila is portraying a character with psychotic shades. Her director is pretty impressed the way she has pulled off her role. Her performance in suicidal attempt scene from a high rise building is par excellence. Her locking horns with Sonali is also of highest order. Also, Urmila is paired with Fardeen Khan for a second time. Jungle was their first movie together. Pyaar Tune Kya Kiya is a rough rehash of the Hollywood potboiler Fatal Attraction starring Michael Douglas-Glen Close.
