He looks skinny and underweight. His cheekbones stick out prominently. His once famed six-packs have become a thing of the past. And, Bollywood superstar Shah Rukh Khan is the first to admit that he's lost weight. Yes, I have lost a lot of weight. I need to put some weight on even the kids, Aryan and Suhana, are thinking I am a 90-pound pushover weakling. I can't be an under-nourished superhero, can I, adds the actor, who is currently busy shooting for his sci-fi superhero flick, Ra. One, which also stars Kareena Kapoor and Arjun Rampal, and is scheduled for release next year.
