Maybe, Modi felt that the performances of Katy Perry and Amitabh Bachchan were not up to the mark.
Or, maybe, that the Bollywood performers lacked zing.
What is certain is that Modi, 48, is bitter about no longer being part of IPL - his brainchild, his claim to fame.
The Modis were once among the wealthiest families in India, a far cry from now. But never before had a Modi hogged so much limelight.
His parents, Bina and KK Modi, recently travelled to South America, where people knew little of India; still, people there knew all about their son!
For three years, around this season, Modi would go into overdrive.
He would be like a man possessed, say those who have seen him closely at work, "irritatingly micro-managing" every little detail of the game which he was determined to take to another level.
In Modi-era IPL, cricket was not just about cricket - it was equally about big money, glitz and glamour, parties, Bollywood, models, cheerleaders and the works.
Suspended by the Board of Control for Cricket in India as IPL chairman and commissioner in April 2010 and accused of corruption and nepotism, he might have made London his home, but it is easy to picture his eyes flashing angrily every now and then as he watches IPL's fifth edition.
