Preity Zinta took a trip down memory lane on Thursday and shared a throwback photo from the time when she received an honorary doctorate from the University of East London. The actress, in the blast from the past, can be seen holding her degree and posing for the camera. "Look what I found in my photos. So grateful to the University of East London for this incredible honour. Now I joke and tell my friends, 'Trust me I'm a doctor' but never use the Doc in my name in honour of all those doctors that worked hard for this achievement," Preity Zinta captioned her post.
