It's a two way street ... Channel knows Sanaya's popularity, they are roping in all the stars they can get to perform, including Sushant, so it is a compliment to Sanaya and a recognition of her talent and her popularity both ... they know these people will draw the audience to watch ... Sushant is a very good dancer, so is Sanaya ...
I for one was not really planning to watch JDJ since Sanaya was not taking part ... especially after the ITS awards fiasco 😡 ... but now I will tune in for the premier night ...
And Sanaya gets to perform on a large platform, because JDJ is a very popular show ... I hope she perform in front of the judges Madhuri, K Jo and Remo ... it's great exposure for her too.
