Just when all seemed unwell between TV actors Sara Khan and Ali Merchant, the couple has shocked everyone by deciding to tie the knot Nov 10 on the reality show "Bigg Boss 4".

The couple was going through a rough patch in their three-year-long relationship, but will now marry in the presence of their parents and all "Bigg Boss 4" contestants. The wedding will take place in the Lonavala house, where contestants have been locked for three months without any communication with the outside world.

Ever since Sara came in "Bigg Boss 4", she was seen getting close to actor Ashmit Patel. But Ali couldn't cope with their closeness and decided to enter the show for a weeklong-stay, starting Wednesday.

In fact, just within a day of his stay, he popped the question, and she said yes.

The housemates are quite thrilled about the wedding and have started talking about the preparations for traditional ceremonies like mehendi, sangeet and the nikah.

The wedding will also see the presence of popular actors from leading shows of Colors.
