While dubbing for the film, Kareena surprised Bhandakar with a birthday cake and also gathered all the crew members to wish the director on his special day.
"I am either working or out on a family trip on my birthday. It was very sweet of Bebo (Kareena) to give me this birthday surprise," said Bhandarkar, who turned 43 Sunday.
Produced by UTV Motion Pictures and Bhandarkar Production, "Heroine" will release Sep 21.
