One’s 50th birthday calls for a big bash. But Aishwarya Rai Bachchan likes doing things differently. On her milestone birthday on November 1, the actor pledged her support to the GSB Seva Mandal, Cancer Patients Aid Association (CPAA), and Smile Train. The GSB Seva Mandal is working towards building a 300-bed, multi-speciality hospital for the underprivileged, in Mira Road. Keen to do her bit, the actor donated Rs 1 crore towards the project.
