As 1 & 3 are enemy no.
Hrithik Roshan is no.1 (10 January 1974)
Kareena Kapoor is no.3 (September 21, 1980)
I dont think their pairing is lucky for filmmakers.
Their films like Yaadein,Mujhse Dosti Karoge!,Main Prem Ki Diwani Hoon were not successful at box office.
Kareena was about to work in Kaho Na Pyaar Hai but was then replaced by Amisha Patel which proved lucky for Hrithik.
Just after Hrithik Roshan bowed out of Karan Malhotra’s project ‘Shuddhi’, his co-star Kareena Kapoor Khan has the followed suit.
Now they both left Karan Johar's Movie Shuddhi in which they were about to work from long time.
So 1 & 3 should avoid each other.
Even Shuddhi adds to unlucky name no.
