Sara Ali Khan and Karthik Aaryan is the new favorite couple of B-town ever since Sara said she crushes on Karthik. These two have been regularly making public appearances be it some launch events or parties. Being paired opposite each other in Love Aaj Kal 2, they have now been told to maintain distance and not make any appearances together by their director Imtiaz Ali. A source revealed - ""Kartik and Sara had been making too many appearances together in public. They have also been making a lot of headlines. It will then take away the charm of the film too soon if the media stops asking them fun questions about each other. Hence Imtiaz Ali has told them to try and keep the exclusivity towards the film's release as it will help the film."
