Aishwarya Rajesh is the latest one to join Gautham Menon’s ambitious project, Dhruva Natchathiram. A source close to the actor said she’s playing an important role, and not a cameo. “Aishwarya’s happy she’s on board. This will be her first collaboration with both Vikram and Gautham. She’s looking forward to working with them. The team will be off to the US in a week and she’ll begin shooting her portions only after that,” the source added. CE hears that the actor hasn’t officially signed the project though. Dhruva Natchathiram has Ritu Varma as the heroine opposite Vikram while Parthiepan is doing a pivotal role.
