Kundan Singh, a politician with a criminal past, says that the producer of reality TV show Bigg Boss (Colors) has approached him for the forthcoming season. "The producer (Endemol) requested me to work in the show. I have asked him to give me some time to decide. I will let him know about my decision when he will call me again," Singh, who is not associated with any political party right now, told reporters here Thursday. If sources are to be believed, the makers of Bigg Boss are keen to rope in at least two real 'bahubalis' with a criminal track record from Bihar and Uttar Pradesh. Singh has allegedly been named in over a dozen criminal cases, including those of murder, kidnapping and extortion. Bigg Boss is aired on Colors and when IANS contacted it, the channel refused to comment. Apart from the actors and models, the controversial show hosted politician Sanjay Nirupam in the second season and cricketer-turned-politician Navjot Singh Sidhu and Gulabi Gang leader Sampat Pal in Bigg Boss 6.
