The reason behind all this is Hrithik's romantic inclination towards Kites co-star Barbara Mori. The couple have been going through a bad phase with their relationship and had been making very few public appearances together. Susanne had initially thought it to be a passing phase and tried to ignore it. But Hrithik's continuous mingling with Barbara forced her to take a call to move in with her parents.
Rumours about Hrithik and Barbara have been the talk of the tinsel town for quite some time now. They would often be too close for comfort during the recent shooting in Mumbai. During the shooting Hrithik had become very close to Barbara and her family and even took them to a trip to Lonavla with Susanne preferring to stay back home.
Hrithik flew back home from South Africa to save his marriage and drove straight to Susanne's house to meet her. Both the families on their part have maintained that there is nothing wrong with Hrithik and Susanne and she has moved in as there are some renovation work at Hrithik's house. Well we all hope Bollywood's most loved and non-controversial couple stick to each other.
