They are part of the big fat Bollywood family. Director Tigmanshu Dhulia and Irrfan, who have been childhood buddies, are now going through a deja vu moment

Apparently their kids too are friends and bond over their school homework.

Apart from working together in the upcoming film Saheb Biwi aur Gangster Returns, the two have ample reason to stay in touch with each other. Says Tishu, `Our friendship has blossomed over the years and we share a great rapport.

Irrfan and I have known each other since our schooldays. We share a special relationship. His son and my daughter were both born in the same year and they go to the same school too. Our bond has been strengthened.`

A source close to the director and the actor says, `Tishu and Irrfan also end up going to their kid's PTA meetings and school functions together.`
