When probed about the reasons, the source close to Sonakshi said that it is just due to her busy schedule and prior work engagements.
The film that stars Aishwarya Rai Bachchan as protagonist also stars south's superstars Nagarjuna and Mahesh Babu. It is also believed that Mani Ratnam even had a word with Sonakshi's father, Shatrughan Sinha and discussed about her role.
It's been almost around three years that Aishwarya has not appeared on screen.
We wish all goes well with the film and Aishwarya!
