Katrina taking singing classes from Farhan

“Farhan is giving me singing classes and I feel this is the best part of him. He taught me to sing in rhythm during the shoot. He’s also a best driver with lots of patience in him,” she said.

Kaif also feels that after working in the film all his co-stars have become “friends for life”.

“They all have become friends for life and I am planing to celebrate my birthday on July 16 (just a day after the release) with them,” she added.
