She brought up the secret of marriage when Salman prompted her whether she knew about his family. Later she said something about astrologer uncle and so on as reason for having heard such a rumour. That did look fishy.
I found her so confusing in this matter. at one point she said clarified that Arhaan had told her about gf who wanted to marry him. I mean then wouldnt her words to Salman have been girlfriend thi or something and not 'marriage'.
No wonder with this and the 1.5 days mei Arhaan ko propose karne ka reasons sunkar Rajat said she cooks up stories.
She had so many days to think about the story and if this is the best she could come up with especially with end of BB interviews coming closer, the she really needs to get clearer about herself.
