Sources say that the 1920 actor Rajniesh Duggall has been signed on for the upcoming adventure reality show Fear Factor - Khatron Ke Khiladi (KKK). “He is the last contestant to be locked in for the show,” says the source. The model-turned-actor was seen in Dangerous Ishq with Karisma Kapoor and was also part of a theatrical drama Ramleela that was hosted by Ajay Devgn. With KKK, Rajniesh will be making his TV debut. It will also give the beefy actor a chance to flex his muscles and do some daredevilry. The show to be hosted by Rohit Shetty will be shot in Cape Town, South Africa. Others who are already on board include Kushal Tandon, Gauahar Khan, Mugdha Ghodse and Nikitin Dheer. This time the format is different from the earlier ones and will pit boys against the girls.
