Bollywood heartthrob Ranbir Kapoor, who belongs to a family of great actors and filmmakers, says while his mother Neetu Kapoor is his biggest fan, his father Rishi Kapoor is his biggest critic.

"My mom is my biggest fan, but my father is my biggest critic," Ranbir told reporters.

"He is someone who will call a spade a spade and is not afraid of hurting anyone because he is very correct when opinions are concerned and I am really happy that I have someone like him in my life who will tell me when I`m bad and when I`m good," he said.

Ranbir, who has acted in films like "Saawariya", "Bachna Ae Haseeno" and "Wake UP Sid" will be next seen opposite Katrina Kaif in the romantic comedy "Ajab Prem Ki Ghazab Kahani", slated to release November 6.
