Hyderabad, Sep 10: Big B Amitabh Bachchan has taken upon himself to clear air of misunderstanding clouds with Kareena Kapoor's film 'Heroine' under Madhur Bhandarkar's direction. Lot of bad blood has flown in when Aishwarya Rai, the first choice heroine for the film walked out of the project after shooting for some time citing pregnancy problems. A furious Madhur alleged that Aish hid the pregnancy issue while signing the dotted lines for the project. Madhur re shoot the scenes after settling for Kareena Kapoor with precious days of shooting lost in the process.

However the film is completed and the film makers are planning to release 'Heroine' on a grand scale. However the entire episode even led to a cold war between Bachchan's and Kareena Kapoor. Sources concede that, Amitabh Bachchan has ended the war by wishing Kareena luck for Heroine, on his show Kaun Banega Crorepati.

The 69-year-old actor decided to use the platform of his reality show Kaun Banega Crorepati to congratulate Bebo on the special day. And that's not all, he also wished her luck for Heroine! It so happened that when a contestant Sameer on KBC told Bachchan he wanted to wish the actor on her birthday. As this particular episode is scheduled to air on Kareena's birthday, Amitabh Bachchan called up Kareena to make Sameer's wish come true. Bachchan himself wished Kareena and gave his blessings for Heroine. The chat between the two stars lasted a few minutes, with everyone on the set listening."

The source further added, "It seems that Kareena herself was initially supposed to go on KBC as a guest, but that didn't work out due to her hectic schedules. So when this opportunity to interact with a contestant on the show came her way, Kareena agreed to interact with her fan and with Big B."
