Karan Johar’s show Koffee with Karan seems to be becoming the favourite platform for Bollywood star -wars. Mallika Sherawat has now joined in after commenting on how she could have done Kareena's item song Yeh mera dil better in Don . Altough seemingly passed off as a joke if the reader studies this in detail the remark wasn’t at all innocent. It’s no secret that there’s no love lost between the two, with rivalry going back to when Mallika was Reema Lamba, and she played Kareena’s best friend and confidante in Vashu Bhagnani’s Jeena Sirrf Tere Liye . A source close to the unit of that long forgotten film says, "The vibes between the two were so cold that the sets would freeze the minute the two actresses walked in.” After the film, Mallika had confessed to a friend, that Bebo had treated her like dirt, adding she was just a nobody, and she made me feel like dirt. Bebo wouldn’t talk to me. Even my hellos went unanswered. I felt miserable. Mallika’s then had a chance to get even when she was offered Murder . The film seemed like another, more erotic interpretation to the theme of marital infidelity that Kareena shot in Bewafaa . "Mallika went around telling everyone that Bebo was doing a film exactly like her Murder . When this reached Bebo’s ears, she was naturally livid. Finally, Murder launched before Bewafaa and proved to be a huge box office success, vindicating Mallika for all the humiliation she had suffered.
