Interesting enmities, envies and hidden rivalries, reported in the Mirror, are enumerated below. 
Jaya Bachchan recently claimed on Koffee with Karan that she loves Shah Rukh, well clearly it's not a sentiment that is widespread in her family. While the Bachchan-SRK war is old by now, the usually politically correct Big B opted to make his stand clear by not extending any olive branch. SRK's closest buddy and one of Abhishek's favourite directors Karan Johar was instead not only invited by also given the task of choreographing the sangeet ceremony.

Amitabh made it clear that he does not like SRK. 
The Bachchans preferred women – they invited Dimple, Twinkle and Rinke but not Rajesh Khanna or Akshay Kumar. So the Kumar couple holidayed abroad instead of Twinkle going solo. 
Rani Mukherjee, Priyanka Chopra, the Kapoor sisters, Vidya Balan, Sushmita Sen, John Abraham and Bipasha Basu were not invited for incredible reasons like past rivalries or relationships or a new top star status (as in John Abraham’s case). 
Hema and Dharmendra were miffed that daughters Esha and Ahna were not invited. Reacting to this snub, both did not attend the wedding. 
Farhan Akhtar, Ravi Chopra, Vidhu Vinod Chopra, Sanjay Leela Bhansali, Sanjay Gadhvi – some of Bollywood’s most successful directors – were not invited for personal dislikes and because they were in the ‘wrong camp’. 
Hrithik Roshan had angered the Bachchans with the lip lock with Ash in Dhoom 2 and thus lost his chance to attend the wedding. 
Abhishek also minded the fact that Hrithik replaced him in Rakesh Om Prakash Mehra’s new film Dilli 6, which AB Corp wanted to co-produce. The deal fell through and Abhishek walked out of the film, making room for Hrithik. 
Hrithik Roshan and Abhishek Bachchan have been childhood friends and have always shared a warm relationship. Unfortunately, the relationship soured when the Bachchans disapproved of the Ash-Hrithik lip lock in Dhoom 2. Abhishek and his family were not happy that Ash and Hrithik shared a hot passionate kiss on-screen. Also, Hrithik walking away with all the applauds in Dhoom 2 did not go down well with Bollywood's first family. Hrithik also walked out of an international performance tour because it was called the Bachchan Show. Probably, Ash wanted to invite Hrithik, but she had to exchange a favor with the Bachchans who had left out Salman Khan and Viveik Oberoi for her sake. She had to omit Hrithik from the list to keep them happy. 

The family even ignored Sushmita Sen, who Abhishek often calls 'didi'. Wonder if it had anything to do with the one-time Ash-Sush rivalry?

Now if all this is confusing to the Janata, that’s ok. The only take we can walk away with is, Bollywood is not One Big Happy Family as it is often portrayed!
