Erika Kaar may be making her Bollywood debut in Ajay Devgn's Shivaay but the Polish actress confesses to being more intimated and star-struck by his star wife, Kajol. Turns out, Kajol has a huge fan following back in Erika's home country. “With Ajay I was like, 'Hello man!' but with Kajol it was like, 'Hello ma'am.' I was trying to be respectful and did not talk much with her. In Poland, when people hear Kajol, they start screaming. Kabhi Khushi Kabhie Gham is huge there,“ Erika reveals, adding that her friends during night-outs dance to the popular track “Bole Chudiyan“ from the Karan Johar directed romantic-drama. Erika first met Kajol on the film's sets in Bulgaria and then again in Mussoorie. “Since I knew Ajay was working so hard on the project, once his family came, we all tried to give them their quality time,“ she reveals.

Shivaay, an action-thriller, is Devgn's second directorial after the 2008 romantic-drama, U Me Aur Hum. Erika has previously worked in Polish TV shows, including Blondynka and Az po Sufit!
