A source that had access to his cell phone revealed that Ranbir has nicknames for the girls on his phone. They go by the names 'Blondie', 'Dusky', 'Vixen', etc.
The source says, "He's a young guy and loves to have his share of fun. Now that he's not committed to anyone, he's on a roll.
All his friends keep making fun of him but RK refuses to change his wicked ways."
