According to Mirror the actress refused to wear costumes designed by the film's stylist, Subarna Ray Chaudhri. She felt they wouldn't do "justice to the scene". This came as a surprise to the unit as such a situation had never cropped up before. Undoubtedly, there was a problem and Kat came up with a solution herself.
Said a source from the unit, "Her director friend, Ali Abbas Zaffar, is keeping her company in London although he isn't involved with the film. Together they went off to Oxford Street to shop for costumes which were a better fit for particular scenes."
Subarna is too senior to be bothered by an actress' tantrums and kept her cool. Meanwhile Kat shopped to her heart's content for the scene which is yet to be shot.
While Kabir remained unavailable for a comment, Katrina told Mirror, "No, this is not true. Subarna has done the looks for the film and I'm very happy with them."
