Looks like filmmaker Karan Johar was all caught up in emotion and nostalgia at the same time as he shared a series of throwback photographs one after the other. Take a look at the images you will find what and who is really close to him. There are images of his parents, his best friend, his 'Student of the year' children, his biological children and the one he shares his 'Lifetime bond' with Shah Rukh and Kajol.
