Not even a week into Colors' "Bigg Boss 4", actors Ashmit Patel and Sara Khan's friendship is there for all to see. And now, Ashmit is even trying to convince Sara to kick the butt.

"Sara apparently started smoking after 'Bidaai'. She smokes about one or two cigarettes a day, but Ashmit tried discouraging her to do so as it is harmful for her health. They have struck a good friendship on the show, " a source told.

Wonder what Sara's beau, TV actor Ali Merchant, has to say!
