"I have taken up the role of Shanti Arora on Sasural Simar Ka. The character seemed very interesting and fits the bill perfectly for me," Karuna said in a statement.
"It is partly inspired from Ratna Pathak Shah's character in 'Jaane Tu...Ya Jaane Na'. I look forward to being part of the show," added the actress, who has featured in shows like Kyaa Hua Tera Vada, Pyaar Kii Ye Ek Kahaani and Chhal-Sheh aur Maat.
In Sasural Simar Ka, her character will be called Shanti Arora, a blend of a modern and conservative mother, who is supportive of her son.
In the hope to get her on-screen son Anurag Arora married, she is on a hunt for a suitable match for him.
The show airs on Colors.
