Kriti Sanon’s sister Nupur has been trying to make inroads into films for a while now, but so far there is no news of her signing any movie. Now, we have learnt that Kriti’s behen has decided to start off with ads just like her elder sis did. Not only that, the two sisters will star together in an advertisement for a hair care brand. A source says that the brand felt that having the Bareilly Ki Barfi actress along with her sister Nupur for the first time in an ad will help them gain more eyeballs.
