On social media, Bollywood's Shahenshah shared some very Kodak-worthy pics of himself with the 'God of cricket.'

Sachin, meanwhile, began his day by playing cricket with children from a non-governmental organisation.
Sachin retired from all forms of cricket in November 2013 during the Test match against West Indies at the Wankhede. He is often spotted at Bollywood's A-list parties with his wife Anjali. A teaser of a film on him, Sachin: A Billion Dreams, was released earlier this month.
