The cast and crew of Tigmanshu Dhulia's upcoming 'Saheb, Biwi aur Gangster' sequel have resorted to drinking buttermilk to beat the heat

Irrfan, Jimmy Sheirgill and Mahie Gill are currently shooting in the interiors of Gujarat for the sequel of Tigmanshu Dhulia's film.

As most of the scenes are being shot outdoors in Baria, over an hour's drive from Vadodara, the rising mercury (up to 45 degrees) is making filming difficult with many parched throats. To beat the heat, Mahie began having the local chaas. She got hooked onto it and now her co-stars as well as several production folk have followed suit!

Says a unit source, "We call it the chaas diet. It's so hot that we don't feel like eating anything. Mahie first began sipping glasses of it. All her meals consist of huge quantity of the yoghurt drink more then food. She even made her co-stars Irrfan and Jimmy take a fancy to it."

Adds the source, "Chaas contains more water than lassi and has the butterfat removed, so it is the perfect thirst quencher. Not a single day passes without endless glasses of chaas for us."

Says Mahie, "As we are shooting outdoors, the heat is unbearable. I am on a thanda chhas diet and it really is our saving grace over here to beat the heat."
