Amitabh Bachchan knows Priyanka Chopra's bedroom secrets. Well, don't get it wrong guys! Amitabh was neighbour to the actress at the hotel in Goa this New Year's eve. Recently, when Priyanka posted something about 'privacy' on a social networking website, Big B subtly replied to her saying he knew what transpired in her room on the night of New Year's! Gosh. we think AB knows something about Priyanka that he shouldn't (and we'd give anything to know). Of course, AB was saying it all in good humour, but PC didn't get the hint until Amitabh spelt it out for her and said, "I was referring to you being my neighbour in Goa'.
