Bihar-based Kumar is currently a participant in dance reality show "Jhalak Dikhhla Jaa 5", and Abhishek came to promote his forthcoming movie "Bol Bachchan" on it.
Kumar's performance was a tribute to 100 years of cinema. Abhishek was touched by the act, and even taught the 'crorepati' winner some dance moves. Both of them danced to the tunes of Abhishek's hip-hop number from "Bluffmaster". The episode featuring both the 'stars' will be aired on Colors Sunday.
