Bollywood superstar Aamir Khan who is still soaking in the success of latest release "Dangal", says he doesn't think he rules the box-office. "I am not a box-office king. I am only Kiran's (his wife Kiran Rao) king," said the actor, who looked to be in the seventh heaven after the huge success of his latest film. Speaking at the success party of the film on Saturday night, Aamir also added that he never chooses films on its potential to do business. "Till today I never signed a film on the basis of its capability to do business. I prefer to choose a film from my heart. All the films I've done till now are those which touched my heart," he said.
