2. Robert Pattinson:
All Robert’s fans are pretty much aware of his hygiene habits. The star admits not taking a shower for weeks. His signature hairstyle is adored by many of his fans but they don’t know the big secret behind his hairstyle. The reason how his hair looks like this is because he doesn’t wash them for months. When asked the reason for this, the actor said that he does not feel the need to. He also confessed having a messy house, he says that his house does not have to be clean, the bed is supposed to sleep and the hair which falls on the bed are supposed to stay there only. While shooting for the Twilight saga, the co-stars on the set used to go crazy because Robert would smell so bad.
