Guess who’s having a blast? Aishwarya Dhanush is on a roll and how! The actress is the assistant director to Selvaraghavan in his upcoming film, ‘Aayirathil Oruvan’. Apart from this, she has also sung a song for the magnum opus. But, what really caught our attention is that she’s now dubbing for actress Reema Sen in ‘Aayirathil Oruvan’. The film would star Karthi, Andrea and Reema Sen in the lead roles with GV Prakash scoring the tunes. The film spans from the 12th century until the present era and also has actor Parthiban playing an important role. Well, a mistress of all trades, eh?
