Nayanthara, who is paired up with Uyyalawada Narasimha Reddy (Megastar Chiranjeevi) in 'Sye Raa', is facing a tough time. If the industry grapevine is to be believed, she is concerned about the sluggish pace at which the film's production works have been progressing.

As per a credible media report, the gorgeous diva is having to allocate extra dates because of the undue delay in the making of the biopic. As such, she could either stand to demand extra remuneration from Ram Charan or forgo some or the other film because of the importance of the project.

Konidela Productions will have to pull all stops to make sure Nayan stays on board. She is one of the very few eligible actresses in South India who can be paired up opposite a senior actor like Chiru. Moreover, she has already shot for some scenes involving even Amitabh Bachchan. As such, she can't be replaced.
