Though Bollywood megastar Amitabh Bachchan didnt like to celebrate his birthday in a grand way, there are reports that the veteran actors family and friends are planning to throw a big party this time on October 11, the day when he will turn 70. According to sources, the preparation for the birthday party have already begun. Amitabh is not the kind of person to throw birthday parties, even if it means the start of a new decade. In fact, he always prefers quiet family dinners where a couple of his close friends come over and join him. However, this time people close to him are leaving no stone unturned to ensure that his 70th birthday is a grand one. The source added, Close friends of the star Abu Jani and Sandeep Khosla are said to be in charge of all the planning, including sorting out the guest list, venue and the food. The fashion designers are also designing some special clothes for Big B for the occasion. The party, which will be arranged at a suburban five-star hotel, is expected to be attended by Mr Bachchans family, friends and well-wishers. However, the Bachchans are also planning another party before October to celebrate the success of Ajay Devgn and Abhishek Bachchans Bol Bachchan, which has reportedly entered the 100-cr club. They are just waiting for the return of Big B from London, who is there for the Olympics and is expected to return only on August 5.
