Rajkumar Hirani has been busy with the post production of 'P.K', starring Aamir Khan. However, the ace director yet has a chunk of shoot to complete.

Sources close to the production share, "P. K. still has some portions that haven't been shot, including a song that will be filmed across India."

The source further shares, "Aamir has to lose weight for the shoot and get a toned body. The shoot will most likely happen in August or September."

Hirani is keeping things ready and once the remaining part is finished the final post production will start.

The last schedule would take about 10-15 days. The team is also currently doing recce and prepping for the shoot.

'P.K' is one of the most anticipated films of the year. It will mark the return of Rajkumar Hirani and Aamir Khan after '3 Idiots'.
