After hearing this you will have to swear on Salman's professionalism!
Well it so happened that when Salman Khan recently turned up on the sets of '10 Ka Dum' with stubble of many days many wondered if he was growing a beard for a role. But it turned out that the reason was more personal than professional.
The fitness freak, one hears has torn a tissue in his back during a training session at the gym and is in great pain, hence the stubble. But the professional that he is, was back on the sets in no time all spruced up, clean shaven and raring to go. The only giveaway was the short breaks he took when the back hurt too much. Like he says ''age is catching up!''
