It has only been off late that the trend of onscreen lip locks have been catching up like fire with A-list actors. However, perfectionist Aamir Khan has always been way ahead of time.

Aamir had made heads turn when he first locked lips with Karisma Kapoor in his film 'Raja Hindustani'. And since then he has got intimate with quite a few co-stars in his films.

Now, the latest to join this list is actress Anushka Sharma, who stars opposite him in Rajkumar Hirani's 'P.K'. 

According to sources, the film has a steamy kiss sequence between the two and apparently, it will be the longest onscreen kiss of recent times.
