Salman Khan turned a year older today, as he celebrated his 53rd birthday at his lavish Panvel farmhouse. With the year coming to a closure, the ‘Bajrangi Bhaijaan’ actor revealed how his mother, Salma Khan, has made a quirky demand from him. “My mother told me a few days ago, four-pack will not work anymore and that I need to get into the six-pack shape. Since my mother has said, I will have to get disciplined. I am going to the gym twice a day and am controlling my diet as well. This demand will work out in a couple of weeks,” revealed Salman. The actor is currently shooting for ‘Bharat’.
