Is S.K of Gustakh Dil inspired by Madhubala's R.K ?

While Siddhant plays the role of S.K (Sagar Khurana), Shahrukh portrays his manager. And a little birdie from the industry whispered in our ears that Siddhant Karnick's character S.K is inspired by that of Madhuabala's R.K (played by Vivian D'sena).

Both the characters are the same with a slight difference as R.K is a superstar while S.K is a star maker. That's the reason why the makers (Ravi Ojha Productions) decided to name Siddhant's character as S.K.
All our efforts to reach Siddhant Karnick were in vain.
