It can't get more official than this. Kiara Advani and Sidharth Malhotra are all set to get married on February 6 and just a day before their big day, a couple of stars were pictured at Mumbai's private airport. On Sunday, we spotted filmmaker Karan Johar at the airport. Karan Johar has worked with both Sidharth Malhotra and Kiara in multiple projects.
