The entire Bachchan family, except Jaya Bachchan, were present at the event. Aishwarya's daughter Aradhaya was also there.
Besides her family, actress Nandita Das, Parmeshwar Godrej and filmmaker Pritish Nandy were also present on the occasion among others.
Aishwarya Rai turned 39 Thursday, so a cake cutting ceremony was also organised for her.
After winning the Miss World crown in 1994, Aishwarya debuted as an actress in Mani Ratnam's 1997 Tamil movie "Iruvar". Later she did Hindi movies like "Hum Dil De Chuke Sanam"," Guru", "Jodhaa Akhbar" and "Devdas".
