Mumbai: Actor Anil Kapoor says that his son Harshvardhan is more hardworking than him, something surprising for him as people often tell him that no one can work harder than him. "I feel that he is more hardworking than me, which is very surprising, because people often tell me that no one can be more hardworking than me. Whether people accept him or not, till now people have only liked the trailer very much, but I can definitely say that he is very hardworking," Kapoor said at the screening of his television show "24". Anil's elder daughter Sonam is a famous actress and younger daughter Rhea is a producer and involved with fashion. But Harshvardhan has been closely guarded before the release of the trailer of his debut film "Mirzya", directed by Rakeysh Omprakash Mehra. And even though the trailer has been launched and Harshvardhan and his leading lady Saiyami Kher featured on a magazine cover, he has not been seen yet at public events. "I never spoke a lot about my son. Several people did not know that he is my son. People would always think that I had only two daughters; so many got shocked that I also have a son. My wife and I said that he should be leading a normal, ordinary life, that he should not be a star son, or a celebrity, so you might have never seen him. He did his schooling and then his education abroad and then returned to India, he was an assistant to Anurag Kashyap and then he immediately started working with Rakeysh Mehra," Kapoor said. "Mirzya" releases on October 7.
