Rumours are abuzz that Kangana Ranaut, who is riding high on the success of her last hit "Queen", has hiked her fee by 50 percent. The actress says she chose to hike her fees as she believes she deserves it. The 27-year-old was present at the launch of the cover of Grazia magazine that features her. Here, on being asked about the reason to hike her fees, she said: "There is no particular reason. I have been working for the last seven years and analysing whatever I have earned till date in this profession, I think I deserve and so I am demanding money. "I don't think I am not worthy of that kind of fee. So that is my personal decision." Kangana made her Bollywood debut with 2006 release hit "Gangster" and since then featured in a number of films and won numerous awards and accolades. Currently, she has almost three films in her kitty. Her last releases were "Queen" and "Revolver Rani". (Source: IANS)
