Karan Johar and Kajol's friendship hit a road block when 'Ae Dil Hai Mushkil' and 'Shivaay' were to clash at the box-office. KJo was the producer-director for 'Ae Dil Hai Mushkil', whereas 'Shivaay' was helmed and produced by Ajay Devgn. 'ADHM' did quite well, and marked KJo's entry to the 100 crore club, however, 'Shivaay' failed to do as good. With the two films clashing at the box-office, it apparently soured Kajol's relationship with Karan.
Both, Karan and Kajol remained mum about their broken friendship back the, but Karan opened up about it in his book - 'The Unsuitable Boy'. Karan in a part of the book opened up his and Kajol's relationship.
Here are a few excerpts from his book:
Isn't is sad that Karan and Kajol are not best friends anymore?
