Even as viewers of Ekta Kapoor's successful show "Naagin" are eagerly waiting for the second season of the supernatural series, speculations regarding the lead pair have started doing the rounds.

While it is known that Mouni Roy will continue to play the protagonist in Season 2, Arjun Bijlani, who was seen as the male lead in the first season, will not be a part of the new instalment. Karanvir Bohra has been approached to play the lead role, India Forums reported.

It was reported earlier that Shakti Arora of "Meri Aashiqui Tum Se Hi" fame had been paired opposite Mouni. However, going by the latest report, Karanvir might be replacing Arjun in the second season.

Also, according to some reports, Mouni would be playing a double role in the new season. The actress would not just reprise her role as Shivanya, but would also play her own daughter, Shivangi, in "Naagin 2."

Meanwhile, the teaser of "Naagin 2," which was released a few months ago, had raised the curiosity levels among fans of the supernatural show. The promo featured lead actress Mouni and a new cast member, whose identity was not revealed in the video.

"Naagin 2" will see Adaa Khan and Sudha Chandran reprising their roles of Sesha and Yamini, respectively. Also, Aashka Goradia, who entered the show in the finale of the first season, will play a pivotal role in "Naagin 2." Rumour has it that popular actor Nandish Sandhu has also been taken on board as Vikram Bhanupratap Singh for the new season.
