Karan celebrates his birthday today (October 11) and as his fans are sending zillions of messages for him on social media, we came across a nice collage made by his fans where he is seen in different phases of growing up from being a toddler to now a grown up man and we must say that he looks adorable!

In an ambience which looks angelic, Karan can be spotted popping a bottle of champagne as a signature of commencing the celebrations.

Karan's family has already made plans of sending him a cake in the BB15 house to wish him the best of birthday
