Swara Bhaskar
Yes, you read that right, and I'm not misinformed.
Swara Bhaskar is daughter of Ira Bhaskar. The member of Central Board of Film Certification (CBFC). A governmental regulating body for the Indian filmmaking industry.
Update: For those who are hurt over seeing their beloved Swara's name:
Well it helps when your mother affects the certification of film. Ira Bhaskar was the member of the CBFC team that ordered the producers of Ranbir Kapoor starrer ‘Rockstar’ to blur a flag that had ‘Free Tibet’ written on it. The CBFC team at that point in time feared that posters of “Free Tibet” would have hurt the sensitivities of the Chinese and harmed the Indo-Sino ties.
Kiara Advani/ Alia Advani
Well, she's great grand daughter of the legendary Actor Late, Ashok Kumar. South-Indian star Sayyesha is Kiara's first cousin. Kiara' aunt is a super model and her mother one of the closest friend of Salman Khan (the mafia bhai of bollywood).
Aamir Khan: So-called perfectionist
Amir khan is son of Bollywood Producer Tahir Hussain. I'm sure very few are aware about this.
Vicky Kaushal
Vicky's father is a bigshot in industry and well-known as a Stunt director in films as well as director for few.
Ranveer Singh
Well, this one tried hard to hide this fact. But he is related to The Kapoor clan of Anil Kapoor.
Update: It has been found that Ranveer Singh’s grandmother was a Bollywood actress in the 1940s. Singh’s grandmother Chand Burke was a popular name in the film industry back then and had done films in both Hindi and Punjabi languages.
So spare and don't defend him. I have no complaint about his acting skills. But I'm just stating the fact here. You can't expect us to stop calling spade a spade.
Lastly, Ajay Devgan
His Father Veeru Devgan was a stunt choreographer And action film director. He was quite a popular name in industry.
Edit: I'm adding Emran Hashmi as someone made request.
Though I majority of know his relationship with Mahesh Bhatt
Emraan Hashmi is son of Mahesh Bhatt's and Mukesh Bhatt's sister.
