"Shweta on with me at 'Koffee with Karan'. Shweta and Karan have been the best of friends from when they were five or six years old!" Amitabh posted on his Twitter page.
The 68-year-old even posted pictures of the three of them together.
While Amitabh looked dashing in a black suit, Shweta looked elegant in an off-shoulder carrot-coloured gown. Amitabh feels very emotional and happy whenever Shweta flies in from Delhi to Mumbai to spend time with them.
"Kids are the most beautiful acquisition of the universe. . . simple, endearing and lovable till the end. . . may god bless them!" added Big B.
