Filmmaker/actor Aamir Khan took his wife Kiran Rao and son Azad to Rajasthan where he will be staying for over a month to shoot for his upcoming film 'P.K.' under the direction of his '3 Idiots' director Rajkumar Hirani.

The shooting has commenced in full swing and everyone has been very busy all this while. Since Aamir saw Kiran on the sets everyday, he realized that her presence could be used in the film too. Hence, the team approached her to do a small cameo in their film.

Kiran was amazed with the offer. But when Hirani and Aamir insisted, she agreed to shoot for the special cameo appearance in the film.

This will be the first time Aamir will be seen with wife Kiran on big screen, though they have worked together in 'Dil Chahta Hai', they didn't share screen space.
