The director will helm a commercial featuring SRK Shah Rukh Khan and Rajkumar Hirani were to unite in Vidhu Vinod Chopra's 3 Idiots.

However, things didn't work out and the duo couldn't work together for various reasons and Raju made history with Aamir Khan. However he has directed SRK, exactly a year after 3 Idiots released.

It is learnt that Hirani has shot an ad with King Khan for a fairness product. This is the first time they worked together and each came away with respect and admiration for the other.

The commercial that goes on air in the coming weeks was shot yesterday at Filmistan. This isn't the Munnabhai director's first ad.

In the past, he's shot ads with Amitabh and Kareena. Initially, Raju wasn't too sure if it was something he wanted to do but has now started enjoying shooting ads in-between his films.

To look after the commercials' work, he has started a new division under the banner of Canvas Films headed by Sanjeev Kishinchandani.
