Ranbir, who was promoting his forthcoming film "Anjaana Anjaani" at an event here to launch a new radio station Oye 104.8FM, said: "I'm very immature and inexperienced as far as love is concerned."
"But if I do more films like 'Anjaana Anjaani' I will understand love better. But till now I don't think I have understood the emotion, " he added.
Talking in context of his film, Ranbir further added that as far as he is concerned, he has not fallen in love with a stranger till now unlike his character in the film that is slated to release Friday.
"Till now I've never fallen in love with a stranger. Till now whenever I've fallen for someone, it has always been someone, whom I knew for a period of time. Lets see what happens in future, " said the 27-year-old actor.
"Anjaana Anjaani" is directed by Siddharth Anand and produced by Sajid Nadiadwala and Sharan Kapoor.
The romantic comedy that also stars Priyanka Chopra and Zayed Khan is about two strangers who meet on a bridge while they are about to commit suicide and then decide to wait for 20 more days and fulfil their last wishes before dying.
"It is a simple love story where the two characters realise what love and responsibility is and get to know each other and themselves too, " said Ranbir.
The actor, who was earlier seen in Anand's "Bachna Ae Hasseno", was also all praise for the director, with whom he is collaborating for the second time.
"Sidharth loves films and he has a very distinct style of filmmaking. He has a stamp of his own. It's not like he is influenced. He is very hard working. Then he loves food so you will get very good food on the sets, which is also a great thing, " the actor said.
