PIX: Ranbir Kapoor's Besharam Birthday

This year, Ranbir Kapoor didn't throw a birthday bash like he's done earlier.

Instead, he spent the big day -- September 28 -- promoting his upcoming film, Besharam.

The actor launched the Besharam.IN collection by Indigo Nation at an event held in suburban Mumbai.

Ranbir was quite the entertainer as he showed off his Besharam dance moves on the ramp.

Directed by Abhinav Kashyap, the film will mark the debut of Pallavi Sharda. The film also stars Ranbir's parents, Rishi and Neetu Kapoor.

The actor, who claims that Katrina Kaif is very special, lost his cool when he was asked if he received any special birthday gift from her.

"You know, there is this phrase in English -- it’s none of your business!” he exclaimed to the media.

Talking about the Besharam collection, Ranbir said, “My look in the movie has a very vibrant, youthful and irreverent feel to it. The Besharam.IN collection from Indigo Nation brings out the spirit of my happy-go-lucky character in the movie very well. I simply love the collection. So go ahead. Flaunt my look. Be bold, be yourself, be besharam."

Ranbir chats with director Abhinav Kashyap.

The actor also interacted with fans, who were present at the occasion.

Besharam will release on October 2.
