Sona had apparently met Kajol and Tanishaa earlier when her make-up was being done in one of the hotel's rooms as she was walking the ramp. The three had lots to talk about and Tanishaa even recalled their Son of Sardaar days.
As Sonakshi had already met Kads and Tanishaa, she did not go up to them again during the fashion show that followed. Onlookers felt that she was looking through Kads. Okay point noted... as they say a picture is worth a thousand words.
