Actor Amitabh Bachchan is all set to host the 15th season of his reality game show Kaun Banega Crorepati (KBC). The show will premiere at 9 pm on Sony Entertainment Television on August 14. Ahead of the premiere, the makers have released interesting previews. In one of the promos, Amitabh shared his thoughts about "jeevan sangini search engine” and said that it is the "most powerful search engine". He mentioned that only a life partner can answer questions like, "Where is the other pair of socks?" or "Where the house key is kept?". In the promo, Big B says, “Jivan sangini ki search engine artificial nahi natural hoti hai.” The caption of the promo read, “Humaare #AmitabhBachchan ji bhi maante hain, duniya ke har search engine se strong hai jeevan sangini search engine.” In another promo, the contestants asked amusing questions to Amitabh Bachchan. They asked him about his social media posts, his favorite actress, and even pointed out that he posts on social media at 2 am. Amitabh had a hilarious reaction to these questions.
