A throwback picture on the occasion of Raksha Bandhan is a must and Abhishek Bachchan made sure to share one of the cutest and most adorable pictures from his childhood with his sister Shweta Bachchan Nanda. (All pictures courtesy: Abhishek Bachchan's Instagram account)

Guess who is that pretty little girl hugging Abhishek Bachchan! Well that's Shweta Bachchan Nanda's daughter Navya Naveli Nanda. Abhishek posted this cute picture saying, 'When did you grow from this to the elegant lady you are today? When did you grow from mamu picking you up from the airport to you coming to pick him up at the airport? When did you grow from mamu singing you to sleep to both of us staying up all night dancing? When did you grow from mamu shopping for you to you being my official shopper? When did you grow to decide that mamu still can't treat you like the little bundle you used to be? When? To my favourite, to my niece, to my Navya.... Happy 20th Birthday little lady. Mamu loves you very much. [sic]'

And that's Navya Naveli Nanda's younger brother Agastya Nanda. Abhishek Bachchan shared this throwback picture on Agastya's birthday and posted this lovely message: 'Do mamu a favour, please... Go back to this size. You're becoming way too tall and are soon going to become the tallest in the family ( a title I hold very dear). Have a great day young man. 17 yrs old! Wow, how time has flown. Love you. [sic]'
