Abhishek Bachchan's surprise for his Paa..

During one of the shoots of Kaun Banega Crorepati 2010, the host Amitabh Bachchan had a pleasant surprise when his son Abhishek Bachchan walked into the sets unexpectedly to wish his dad all the luck!!

Says our source, "Abhi was apparently shooting in the same location and decided to wish his dad luck, before his shoot. The audience was jubilant when they saw Abhishek on the sets. They waved and cheered when both the Bachchans hugged and wished each other luck. Abhi took time to wave back to the audience before he left".

With KBC out beating every other non-fiction show and registering a remarkable opening, Abhishek Bachchan on Twitter has commented, "Just got to know that KBC blew the ratings out of the water!!! Proud day to be a son! The big man shows us yet again how it should be done".

Well, Abhi is indeed savouring every moment of his dad's success on the hot seat of KBC!!
