<em>Bigg Boss season 5 </em> is coming to its end. Only six contestants are left and soon the world will get to see the winner of this season which has been replete with drama, catfights and emotional upswings. Now, today is day 87 and here’s an exclusive sneak peek into tonight’s episode (28 December 2011). The day will open with a very lively song <em>Tunak Tunak</em> to which every contestant will be seen grooving. The Punjabi song will hit off a conversation between the two Punjabi kudis in the house – Mahek and Sunny, as Mahek will ask Sunny about her family background.
