The newcomers were presented for the first time at the music launch of the film which releases on November 9. They were introduced by Salman Khan and Rani Mukherji, who play guest roles in 'Saawariya'.
Ranbir, aware of the Kapoor legacy and his debut film which Bhansali said was a tribute to the RK banner, was visibly nervous on stage. He said he would work hard to prove that he was worthy of his family name.
Sonam could not hold back her tears and wept on Bhansali's shoulders. When asked whether her taking centrestage as a leading lady would mean her dad Anil Kapoor would now have to content with fatherly roles, the doting daughter said her father would continue to be 'Lakhan' (his character in the film Ram Lakhan) and a leading man.
''He is more energetic than me. I am just in my early 20s. But he works out for two hours more than me every morning,''she said.
The music was launched by Anil and Rishi Kapoor in the presence of their respectively family members. Rishi Kapoor's brothers Randhir, Rajiv, sister Reema Jain and her family, Natasha Nanda daughter of Rishi's elder sister Riu Nanda and the Kapoor matriach Krishna Raj Kapoor were present.
Anil Kapoor's father Surinder Kapoor, brother Sanjay Kapoor and his family, Arjun, son of Boney Kapoor were present to cheer Sonam.
Ranbir's mother Neetu Kapoor and Sonam's mother Sunita Kapoor were also called on stage by Bhansali.
