Aamir Khan may say, "Love is a Waste of Time", but he can't keep his eyes off Anushka Sharma in the latest song from their upcoming movie PK. PK stares at his Jagat Janini in the rear view mirror as he rides pillion with her, he can't concentrate on his work when she's watering the plants and hears little of what she says on a trip to a historical place - so enchanted is he by her face. And though pyaar is a waste of time, PK and girlfriend with the pixie cut decide that they want to "waste their time" at least once in their lifetime. And so, PK and Jagat Janini, who look made for each other, paint the town red, in this foottapping song crooned by Sonu Nigam, Shreya Ghoshal with music by Shantanu Moitra.
