Bollywood actress  Kajol who  had  until recently restricted herself to roles in front of the camera,  seems to have  changed her mind. This time, she is entering marketing .  You may recall  that  last time  she was seen with Shah Rukh Khan in `Dilwale`.   Later,  she evinced an interest in some of the behind-the-scene activities of her husband Ajay Devgn`s next directorial venture `Shivaay`. It is said that even as Ajay is busy in his role as actor-director, his star wife is getting involved with the film`s marketing.
