Imran Khan and Avantika Malik's rock steady marriage has now hit troubled waters after it was reported that the couple have been living separately for sometime now. Due to growing differences between Imran and Avantika, the latter left the actor's home with daughter Imara. Since then, both of them have dodged the media and not answered the boiling question - what caused the split? But Imran's mother-in-law Vandana Malik responded to rumours and dismissed them completely.
