The line-up of contestants for "Bigg Boss 4" has a Pakistani terrorist's former lawyer, a thief-turned-detective, a former dacoit, a Pakistani cross-dresser and others. It's no wonder Colors chose Bollywood star Salman Khan to host the reality show, where controversy seems to be the ticket for entry.

It seems the "Bigg Boss 4" house in Lonavala, at the outskirts of Mumbai, might end up being quite a pot full of controversies this year with inmates like Mumbai terror attack accused Mohammad Ajmal Kasab's former lawyer Abbas Kazmi; thief-turned-detective Devinder Singh alias Superchor Bunty; actor Ashmit Patel, who was involved in an MMS scandal; and Rahul Bhatt, who was friends with David Headley, accused of scouting targets for Mumbai attack.

There will be fireworks in the house with former woman bandit Seema Parihar, who had allegedly killed 70 people and abducted over 200 before surrendering to the police a few years ago, joining others.

Some controversial names from across the border like Pakistani actress and former girlfriend of fast bowler Mohammed Asif, Veena Malik, and Pakistani cross-dressing diva Begum Nawazish Ali will also spice up the reality show, especially when they will be sharing the same house.

The show's glamour quotient will shoot up with TV actresses like Shweta Tiwari and Sara Khan, former MTV Splitsvilla contestant Sakshi Pradhan and model Aanchal Kumar. Also, joining the inmates will be Bhojpuri superstar Manoj Tiwari, model-turned-actor Sameer Soni and model Hrishant Goswami.

The 14 participants will be spending three months sans any communication with the outside world. They will clean wash rooms, will wake up early morning and survive on limited food.

The participants are not allowed to carry mobile phones and there will be no clock in the house which will be constantly under surveillance of about 50 cameras.

As compared to the earlier editions of the show, the set up of the house has been changed along with some rules. There will be no walls, no separate bedrooms for male and female contestants respectively and there will be cameras and microphones in wash rooms.

The colour scheme is brighter with yellow being the dominant shade of the interiors.

Every week a participant will be eliminated, and the one who survives till the end will be the winner.

The launch episode of the season saw a melange of participants taken on a guided tour of the house by Salman, who even performed later on songs from his hits "Dabangg" and "Wanted".

The contestants for the fourth season put up sizzling performances before entering the "Bigg Boss" house.

"Bigg Boss 3" winner Vindu Dara Singh and former contestants like Ravi Kishan, Bakhtiyaar and Tanaaz Currim, comedian Raju Srivatsav, were also present at the launch, and some like Kashmera Shah and Sambhavana Seth even performed.
