Whenever 'Koffee with Karan' goes on air, one person who is bound to get angry is Rishi Kapoor.

In the earlier season, Sonam Kapoor  and Deepika Padukone had got on a coffee session with Karan Johar and had spilled the beans on how Ranbir Kapoor is a cheater.

This season, Karan invited Kareena Kapoor Khan along with Ranbir and was hoping to show the world some 'cousin bonding'.

Kareena who is known for being outspoken, joked that she would like to dance on 'Chikni Chameli' and 'Sheila Ki Jawani' at Ranbir's wedding.

Kareena even went further and called Katrina Kaif her 'Bhabhi', a reason why Rishi Kapoor got very upset.

While Ranbir is very serious about settling down with Katrina, dad Rishi does not approve of this relation as he is not comfortable with Miss Kaif's family background. Also, the fact that Katrina had done semi-nude photo-shoots in London before coming to India, is very upsetting for him.

Rishi wanted few portions to be edited from KWK show; however Karan refused to do so.

Now every time Karan raises a cup of coffee, we see steam coming out of Rishi Kapoor's ears.
