What is Ranbir Kapoor busy with? He is busy reading rockstar Curt Kobain's biography so that he can connect well with his character in Imtiaz Ali's "Rockstar".

"I'd rather read about a person who has done something exceptional than a work of fiction because I am part of an imaginary world anyway. Scripts are fiction, so this is my connect with reality, " said Ranbir in a statement.

The 28-year-old was earlier seen in hits like "Raajneeti", "Bachna Aae Haseeno" and "Wake Up! Sid".
