Last year also, Kareena missed out on celebrating her birthday as she was shooting for the film 3 Idiots. And this year too, there were speculations that Kareena would be working on her big day.
A birdie informs that Aamir arranged for a cake on the sets of the film and also postponed the shoot, so that Bebo can take out some time for Saifu.
According to reports, the shooting will go on till October 2, 2009.
That's why we call Aamir a perfectionist!
