"I am ashamed of my behaviour. I lost control of my emotion. Whatever was shown on TV was not my natural self.I don't know what happened to me at that time. I had no intentions of garnering negative publicity," Imam said.
He will join two new contestants in the mud house -- Jyoti Amge, who is world's shortest woman, and 'Chandrakanta' actor Santosh Shukla. The other housemates in the mud house are Aashka Goradia and Bhojpuri actor Dinesh Yadav 'Nirahua'.
"I chose to return because I want to show people that I am not a maniac. I was over-confident about myself and that ruined my reputation. I will be more patient and calmer and treat my two new friends as my family," he added.
Imam, who had a tiff with Aashka a night before he was thrown out, said he has no grudges against the TV actress.
"I watched my conduct later and understood the fact I was over-reacting. Aashka is a lovely lady. She cooks for everyone in the house," he said.
