Apparently this was in retaliation to Kareena's comment some weeks ago about John being 'expression-less' in the same show.
The seeming pay-back is supppsed to add fuel to fire of the whole Kareena-Bipasha war that goes back to the shoot of Abbas-Mustan's Ajnabee where the two actresses had exchanged harsh words over Kareena's costume designer lending his talents to Bipasha without Kareena's consent.
Kareena started the bitch fight by saying she would not like to work with John Abrahams because she found his face 'expressionless.'
Bipasha however denies she was nasty about Kareena. "I would never do that. I'm not that kind of person," she says and adds, "I certainly don't believe in hitting back at anyone. And my episode of Koffee With Karan which was telecast on Sunday was recorded in the first week of December, when I had no clue what Kareena would say about John.
In any case, people are entitled to their opinion. If Kareena thinks John is expression-less then so be it. He's a grown-up man. He can fight his own battles. I certainly won't jump in the fray for anyone else, not even my boyfriend. I don't wish to start a war of words with Kareena or anyone else."
