When a special guest is in town, you can trust B-town to put on their party hats and spin a good mix of glitz and glamour. And talking of parties, the Ambanis know exactly how to host one. The Mayor of London, Sadiq Khan, is in Mumbai and the Ambanis threw a lavish party to welcome him.

The who's who of Bollywood was present and even the mayor could not help but get clicked with the stars.

Great to meet British Bollywood superstar @KatrinaKaif. Her success is yet another example of the deep connection between our two great cities and our booming film industries. #LondonIsOpen
