Bollywood superstar Amitabh Bachchan, who underwent treatment for 'diverticulitis' at the Leelavati Hospital for nearly three weeks, was discharged from the hospital on Saturday morning. Dressed in a white 'kurta-pyjama', Bachchan stepped out of the hospital with his children Shweta and Abhishek and was also accompanied by his close friends - Samajwadi Party leader Amar Singh and industrialists Anil Ambani and Subroto Roy. The 63-year-old megastar looked weak, but was cheerful as he stepped out of the hospital. He first greeted the waiting mediapersons with folded hands and then waved to them before getting into his car. He then headed straight to meet his mother Teji Bachchan, residing at 'Prateeksha' bungalow in Juhu. This was the first time since Amitabh's near-fatal accident on the sets of Hindi film 'Coolie' in 1982 that he has spent such a long period in hospital.
