Confusing as it sounds, it’s true. Kiara Advani's real name is not Kiara. She revealed this in an episode of Voot's "Feet Up with the Stars Season 2".
Kiara's actual name is Aaliya. Now there is already an Alia Bhatt in Bollywood. There cannot be two actresses with the same sounding names. It was Salman Khan who suggested Kiara (Aaliya) to change her name. That's when the actress adopted a new name Kiara.
Now this has become her name. It seems even her parents call her Kiara now. The actress has been seen in popular films like Bharat Ane Nenu and Vinaya Vidheya Rama in Tollywood. In Bollywood we would be seeing her in Good News, Kabir Singh, Shershaah and the Kanchana remake.
