So much is being made of Amitabh Bachchan`s 60th birthday. But since that is the case, here`s a bit more on it. Last heard was that on Big B`s birthday, his son Abhishek Bachchan and scion of the Bachchan family would formally get engaged to Babita and Randhir Kapoor`s elder daughter, Karisma Kapoor.

Now, there`s a slight change of plan. The engagement date has now been shifted to an undecided date. Babita and Kareena`s unavailability resulted in the change of plan. Apparently, little sister Kareena is busy with her shooting schedule in New Zealand and will not be able to wrap up things before the schedule date. She is shooting nonstop for Sooraj Barjatya`s Mein Hoon Prem Deewani which incidentally also stars her brother-in-law to be Abhishek Bachchan.

Apparently, the Big B himself was not very keen on the `big bash for the Big B` bit of it. His parents` are very unwell. So much so that news of Abhishek`s engagement to doesn`t register well with them, says the Bachchan senior. But at the insistence of his other family members and friends he has agreed for a bash at the Marriot Hotel, Mumbai.
