Dhoom fans may have to wait even longer before the film goes on floors. Despite being one of Yash Raj films' biggest ventures and certainly the most-anticipated one, Dhoom: 3, Dhoom: 3 has got delayed once again due to villain Aamir Khan.This is the third time that Aamir has postponed the film - first it was for Reema Kagti's Talaash and then the actor got busy with his debut TV show Satyamev Jayate. Months later, the actor has done it again and this time it's because of his hair!Yes, you read right. Mr Perfectionist is reportedly taking time for getting the right hairdo. Well, we know it's worked in the past (Dil Chahta Hai, Rang De Basanti, Ghajini or even Taare Zameen Par) and we guess it'll work once again.After all, there's nothing in the 200 crore film that can go wrong!
