Actress Nayanthara, who was last seen on-screen playing a double role in horror-thriller "Airaa", has been signed as the leading lady opposite superstar Rajinikanth in his next yet-untitled film with filmmaker A.R. Murugadoss.

On Monday, Rajinikanth's publicist Riaz Ahmed took to Twitter to confirm Nayanthara is on board. He also denied other casting reports that have been doing the rounds.
