As we all know, Superstar Rajinikanth's mega budget sci-fi entertainer '2.0' is presently being shot in Jawaharlal Nehru Staidum in New Delhi. Rajinikanth and Bollywood superstar Akshay Kumar who plays the lead negative role in the flick are taking part in a fight sequence.

Last week veteran Bollywood actor Amitabh Bachchan and his song and actor Abhishek Bachchan were spotted in the '2.0' shooting spot and that lead to speculations that the father son star duo are playing a cameo in the costliest Tamil film ever.

Now an official source for the '2.0' unit has refuted this as mere rumor. Amithabh and Abhi had actually visited the shooting spot just to meet their good friends Shankar and Rajinikanth to wish best for the film. Abhishek also met his Bollywood colleague Akshay Kumar and was chatting with him. This however lead to the rumor about their participation in the film which is not true.
