The perfectionist Khan is at it again! The actor who plays a character half his age in 3 Idiots is losing weight for a lean look. For his role, he's taking tips from two people - Mansoor Khan's teenage son Pablo and his Ghajini director AR Murgadoss.

The actor not only had to work on his physique but also his mind, body language and even his wardrobe. To get under the skin of his character, the actor says he started observing kids. “Many of them were my son Junaid’s friends," he admits. "I would closely observe how they talk, walk and behave."

Aamir is fascinated by the way Pablo is always moving on his feet, not even stopping to talk. "Pablo is so fidgety that he can’t stand still even for a few minutes."

The actor also got inspired by his Ghajini director AR Murgadoss a bit. "I love the boyish sparkle in his eyes… he always has a twinkle in his eyes and is full of excitement."

Aamir says that he had keenly observed that the puny Murgadoss always wears worn-out clothes and T-shirts that are two sizes too large.

“Yaar, first I had to work very hard to get those eight packs for Ghajini and then I had to work doubly hard to lose that dream physique and look lean," says the actor. He confesses that he also borrowed a couple of oversized T-shirts from his Ghajini director.
