'You can't be too thin,' says Sonam

How did you celebrate your birthday?

Last year, on my birthday I was shooting for Saawariya. And this time I was shooting for Dilli 6.

There are stories your Dilli 6 director Rakeysh Mehra bullied you...

What nonsense! Rakeysh is a lamb. He is incapable of screaming at anyone. We get along like house on fire. I instinctively understand how he wants me to do a shot.

And what about your hero, Abhishek?

He's tall enough to suit me on screen. It was different during Saawariya as my relationship with Ranbir was casual as we are childhood friends. However, with Abhishek, I was a thorough professional. He made suggestions gently and if he wanted to make a point, he said it as a joke to avoid any offence. And we both love junk food. He would keep digging into my cookies and then blame me for his weight gain. He has done 35 films, which he keeps reminding me all the time. Besides that, we are from similar backgrounds, both of us have studied abroad and we both have been brought up in Juhu. And I am in awe of Ash – she is so beautiful!

What about you and Ranbir?

I was never seeing Ranbir. I'm happy for him. Deepika seems to be a really nice girl.

Any more films with him?

We've got no offers together. But I'm sure we will work together again. We share a great chemistry on screen.

Would you like to be a size zero for your birthday?

I lost 35 kgs for my first film. Even if I starve myself I'd never be a size zero. But I believe there's nothing like being too successful or too thin.
