Karan, 30, who gained popularity in showbiz with Kapoor's shows like 'Kasturi', 'Kasamh Se' and 'Kkavyanjali', said she is a mentor.
"Ekta is the guiding force in my life. I have always listened to her as she has given a new high to my career. I share a comfort level with Ekta. I have always believed in her," Karan told PTI.
With the show, which will go on air from December 3 on Star Plus, Karan is making a comeback in fiction after four years.
'Ye Hai Mohobbatein' is a love story of a middle-age man and a young girl. The story begins after a marriage gets over and explores the theme of a second chance in love.
"Portraying the character (Raman Bhalla) was a challenge for me. He is a rich businessman with a daughter from his failed marriage. The role is much older to my original age," he said.
