Bigg Boss 7: The curious case of Gauhar Khan's 'Saree Ka Fall'

In today's episode, Gauhar and Kushal tease Sangram saying that they will make him dance for an item number. They then go ahead and sing the 'Saree Ka Fall' song from the movie 'R Rajkumar'. Now, the strange thing is that though Kushal might have learnt it during his time outside the house, how in the world did Gauhar learn the song which release a month after Bigg Boss 7 took off?

Did she learn it from Kushal? However, she was not even struggling with the lyrics and seemed to know it really well. Do you not find this strange?

Gauhar Khan was out of Bigg Boss house for a couple of days too. However, she and the Bigg Boss team announced that she did not have access to phone, TV, Internet or any contact with the outside world during the time.
