One of the rumours said that it was Karishma’s mother Babita who was instrumental in breaking this match as she was not sure if Abhishek Bachchan will be able to provide for her daughter. So she apparently asked the senior Bachchan to provide with guarantee that most of his possessions will be passed on to Abhishek. And Amitabh disagreed to do that.
Another rumour was that Lolo was not happy at being asked to stop being an actress after marriage by the Bachchans.
However, looks like no one would ever know the real reason, except the parties involved, as everyone has been keeping mum about it.
The only revelation was from Jaya Bachchan as she said in an interview that parents are not to be blamed for the split as Abhishek had reached the difficult decision of breaking the engagement on his own.
Abhishek eventually fell in love with Aishwarya Rai during the making of Dhoom 2 and the two announced their relationship after the next release Guru. The two got married in 2007 and the couple is now a proud parent of cute little Aaradhya.
