Not too many people know how emotionally vulnerable Saif Ali Khan has become in recent months. The departure of ladylove Rosa has left him more attached to his two children Sarah and Ibrahim than ever before.

It was under these vulnerable circumstances that Saif found himself bonding with two child actors Angelina Idnani and Haji Ali in New York while shooting for Yashraj Films' ready-to-release "Tara Rum Pum Pum".

The two little actors not only regaled Saif throughout the extended three-month-long shooting schedule in New York, they virtually served as anchors and a great source of solace during those months of solitude.

"I really did miss Sarah and Ibrahim while shooting there. The two kids, who play Rani (Mukerji) and my children in 'Tara Rum Pum Pum', were absolutely amazing on and off camera. They were not only the same age as my own children, they even kind of resembled them! For the first time I found myself quite attached to my little co-actors. So much so that I miss them now after shooting," Saif told.

Saif has been spending a great deal of his time with his children.

"That's partly because I was recovering after my illness at home. Now that I'm getting back to work, I won't have that much time for them, and that's a regret. I don't like to have them over on the sets. But I'll make sure I've time for them. That's one of the main reasons why I won't be working on Sundays any more."
