Season four saw incessant verbal abuses hurled over trivial matters, a sensation caused by the televised wedding of participant, actress Sara Khan with her beau Ali Merchant, and then the government hauling it up for "offending good taste.”

Television actress Shweta Tiwari finally emerged the winner and walked away with the trophy and a cash prize of Rs. 10 million at a befitting, star-studded finale.

It started with 14 contestants, including 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; former dacoit Seema Parihar and filmmaker Mahesh Bhatt's son Rahul Bhatt, who was friends with terror operative David Headley, accused of scouting targets for Mumbai attack.

There were two contestants from Pakistan — actress and former girlfriend of fast bowler Mohammed Asif, Veena Malik, and cross-dressing diva and television personality Begum Nawazish Ali, apart from Indian TV actresses, Shweta Tiwari and Sara Khan, former MTV "Splitsvilla" contestant Sakshi Pradhan and model Aanchal Kumar, who hardly managed to raise the glamor quotient.

Others who participated in the competition of survival in a secluded house without any communication with the outside world, were Bhojpuri superstar Manoj Tiwari, model-turned-actor Sameer Soni and model Hrishant Goswami, later joined by WWE wrestler, The Great Khali and subsequently by the boisterous Dolly Bindra.

Hollywood bombshell Pamela Anderson was flown in to raise the mercury level as a special guest for three days on the already heated show!

This season courted quite a few controversies and troubles — starting Day 1 with Superchor Bunty's ouster following unruly behavior in the house. Then followed objections by the Shiv Sena and Maharashtra Navnirman Sena (MNS) against inclusion of Pakistani celebrities on the show. The entry of The Great Khali, whose humungous size of 7'1 and heavy voice, sent jitters down the spine of other contestants. The atmosphere in the "Bigg Boss 4" house was quite calm, cool and friendly until Dolly Bindra made a wildcard entry, and shook the atmosphere with her loud and overbearing nature.

Abuses, fights and melodrama became a way of life after Dolly and Shweta began to settle personal scores violently. The fights got others like Ashmit, Sameer, Khali, Veena, Sara and Manoj involved too. In fact, Sameer and Dolly were asked to leave the show for their bad behavior, only to return a few days later. Where ill will was flourishing between many, romance was also in full bloom with Rahul-Aanchal's silent chemistry, Veena's one-sided attraction for Hrishant as well as Ashmit and Sara's growing closeness there for the public to see.
